C# EndpointNotFoundException未处理（WCF）

我按照这本图图在我的sql server和我的c#app之间部署WCF：

这是我计划的一部分：

IService1：

namespace WCFCrud
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IService1
    {

        [OperationContract]
        Int32 Insert(WCFContact value);

        // TODO: Add your service operations here
    }


    // Use a data contract as illustrated in the sample below to add composite types to service operations.
    [DataContract]
    public class WCFContact
    {
        private Int32 contactID;
        private String contactName;
        private String contactAddress;
        private String contactNumber;
        private DateTime contactDOB;
        private Decimal contactIncome;

        [DataMember]
        public Int32 ContactID
        {
            get
            {
                return contactID;
            }
            set
            {
                contactID = value;
            }
        }
        [DataMember]
        public string ContactName
        {
            get
            {
                return contactName;
            }
            set
            {
                contactName = value;
            }
        }
        [DataMember]
        public string ContactAddress
        {
            get
            {
                return contactAddress;
            }
            set
            {
                contactAddress = value;
            }
        }
        [DataMember]
        public string ContactNumber
        {
            get
            {
                return contactNumber;
            }
            set
            {
                contactNumber = value;
            }
        }
        [DataMember]
        public DateTime ContactDOB
        {
            get
            {
                return contactDOB;
            }
            set
            {
                contactDOB = value;
            }
        }
        [DataMember]
        public decimal ContactIncome
        {
            get
            {
                return contactIncome;
            }
            set
            {
                contactIncome = value;
            }
        }
    }
}

我的服务1.cs：

namespace WCFCrud
{

    public class Service1 : IService1
    {
        string ConString = "Server="ServerAdress";Database="DatabaseName";Trusted_Connection=True;";
        public int Insert(WCFContact ContactPar)
        {
            using (SqlConnection con = new SqlConnection(ConString))
            {
                using (SqlCommand cmd = new SqlCommand("dbo.InsertContact", con))
                {
                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.Parameters.Add("@ContactName", SqlDbType.VarChar, 100).Value = ContactPar.ContactName;
                    cmd.Parameters.Add("@ContactAddress", SqlDbType.VarChar, 100).Value = ContactPar.ContactAddress;
                    cmd.Parameters.Add("@ContactNumber", SqlDbType.VarChar, 100).Value = ContactPar.ContactNumber;
                    cmd.Parameters.Add("@ContactDOB", SqlDbType.DateTime).Value = ContactPar.ContactDOB;
                    cmd.Parameters.Add("@ContactIncome", SqlDbType.Money).Value = ContactPar.ContactIncome;
                    con.Open();
                    var ID = cmd.ExecuteScalar();
                    ContactPar.ContactID = Convert.ToInt32(ID.ToString());
                }
            }
            return ContactPar.ContactID;
        }
        public int Update(WCFContact ContactPar)
        {
            using (SqlConnection con = new SqlConnection(ConString))
            {
                using (SqlCommand cmd = new SqlCommand("dbo.UpdateContact", con))
                {
                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.Parameters.Add("@ContactID", SqlDbType.Int).Value = ContactPar.ContactID;
                    cmd.Parameters.Add("@ContactName", SqlDbType.VarChar, 100).Value = ContactPar.ContactName;
                    cmd.Parameters.Add("@ContactAddress", SqlDbType.VarChar, 100).Value = ContactPar.ContactAddress;
                    cmd.Parameters.Add("@ContactNumber", SqlDbType.VarChar, 100).Value = ContactPar.ContactNumber;
                    cmd.Parameters.Add("@ContactDOB", SqlDbType.DateTime).Value = ContactPar.ContactDOB;
                    cmd.Parameters.Add("@ContactIncome", SqlDbType.Money).Value = ContactPar.ContactIncome;
                    con.Open();
                    var ID = cmd.ExecuteNonQuery();
                    return ID;
                }
            }
        }
        public List<WCFContact> SelectAll()
        {
            List<WCFContact> SelectList = new List<WCFContact>();
            using (SqlConnection con = new SqlConnection(ConString))
            {
                using (SqlCommand cmd = new SqlCommand("dbo.SelectAllContact", con))
                {
                    using (SqlDataAdapter da = new SqlDataAdapter(cmd))
                    {
                        cmd.CommandType = CommandType.StoredProcedure;
                        DataSet ds = new DataSet();
                        da.Fill(ds);
                        if (ds.Tables.Count > 0)
                        {
                            foreach (DataRow dr in ds.Tables[0].Rows)
                            {
                                SelectList.Add(new WCFContact
                                {
                                    ContactAddress = dr["ContactAddress"].ToString(),
                                    ContactDOB = Convert.ToDateTime(dr["ContactDOB"]),
                                    ContactID = Convert.ToInt32(dr["ContactID"]),
                                    ContactIncome = Convert.ToDecimal(dr["ContactIncome"]),
                                    ContactName = Convert.ToString(dr["ContactName"]),
                                    ContactNumber = Convert.ToString(dr["ContactNumber"])
                                });
                            }
                        }
                    }
                }
            }
            return SelectList;
        }
        public int Delete(WCFContact ContactPar)
        {
            using (SqlConnection con = new SqlConnection(ConString))
            {
                using (SqlCommand cmd = new SqlCommand("dbo.DeleteContact", con))
                {
                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.Parameters.Add("@ContactID", SqlDbType.Int).Value = ContactPar.ContactID;
                    con.Open();
                    var ID = cmd.ExecuteNonQuery();
                    return ID;
                }
            }
        }
    }
}

和我的应用程序配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
    </startup>
    <system.serviceModel>
      <bindings>
        <basicHttpBinding>
          <binding name="BasicHttpBinding_IService1" />
        </basicHttpBinding>
      </bindings>
        <client>
            <endpoint address="http://localhost:20570/Service1.svc?singleWsdl" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceRef.IService1"
                name="BasicHttpBinding_IService1" />
        </client>
    </system.serviceModel>
</configuration>

经过一些搜索，我找到了一个主题，可以改变我的行 http://localhost:20570/Service1.svc 但一切都没有改变

如果有人知道我能做什么

---

非常感谢

您必须在ServiceRef.Service1Client objClient=new ServiceRef.Service1Client（）中将端点名称作为参数传递

---

EndpointNotFoundException仅在客户端未找到它时发生，因此我们必须显式传递参数名称。它适合我

你的地址应该是

http://localhost:xxxx/Service1.svc

如果有，xxxx是您的端口。现在，如果您使用的是IIS Express或其名称，那么您的端口无疑与

20570

不同。在调试器中运行服务，并注意Windows系统托盘中的端口。将该端口插入客户端配置。如果将您的服务托管在IIS中，则寻址会变得简单得多（即http://localhost/Service1/Service1.svc），并且不会每次都更改。是的，端口号为20570，我将地址替换为，但我仍然有相同的消息使用“添加服务引用”将引用添加到您的Web服务。如果发现按钮位于同一解决方案上，则可以使用该按钮。尝试更改

ServiceRef.Service1Client objClient=new ServiceRef.Service1Client（）

并调用以endpointName作为参数的构造函数的重载。我已经添加了我的服务引用，但现在忘记更新了。它正在工作，谢谢您的帮助
