C# 如何将参数作为调用WCF DataContract的对象传递

l -这是我的WCFSeviceLibrary接口类

在此接口中，将OperationContract中的IService1类声明为一个ObjectClass类型方法

并为集合类型创建此ObjectClass类。作为甘尼瑞克

    public interface IService1
        {               
             [OperationContract]
             ObjectClass SetDataUsingDataContract(ObjectClass data); 
        }
    [DataContract]
        public class ObjectClass
        {
            string name;
            string address;
            string emailid;
            double contactno;
            [DataMember]
            public string Name
            {
                set { name = value; }
                get { return name; }
            }

            [DataMember]
            public string Address
            {
                set { address = value; }
                get { return address; }
            }

            [DataMember]
            public string EmailId
            {
                set { emailid = value; }
                get { return emailid; }
            }

            [DataMember]
            public double ContactNO
            {
                set { contactno = value; }
                get { return contactno; }
            }

        }

Service.cs文件 在这个类中，Implimate

public class Service1 : IService1
    {
 public ObjectClass SetDataUsingDataContract(ObjectClass data)
        {

            SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=D:\Pavan\WCF_Practice\WcfServiceSample\WebApplicationvc\App_Data\WCFDB.mdf;Integrated Security=True;User Instance=True");
            conn.Open();
            SqlCommand cmd = new SqlCommand("INSERT INTO WCFTBL (Name, Address, ContactNo, EmailID) VALUES ('"+data.Name+"','"+data.Address+"','"+data.ContactNO+"','"+data.EmailId+"')",conn);
            cmd.ExecuteNonQuery();
            conn.Close();
            return data;
        }
}

这是我的Btn_点击类Web应用程序页面

 protected void Add_Click(object sender, EventArgs e)
        {
            ServiceReference1.Service1Client srv = new ServiceReference1.Service1Client();


            srv.SetDataUsingDataContract();

}

我不知道如何设置srv.SetDataUsingDataContract（）方法的参数

AppConfig文件

<configuration>
  <system.web>
    <compilation debug="true" />
  </system.web>

创建一个

ObjectClass

实例，并将其作为参数传递给

SetDataUsingDataContract

。例如：

protected void Add_Click(object sender, EventArgs e)
{
     ServiceReference1.Service1Client srv = new ServiceReference1.Service1Client();

     ObjectClass objectClass = new ObjectClass();
     // Set properties 
     srv.SetDataUsingDataContract(objectClass);
}

客户端生成代码应该已经创建了一个

ObjectClass

类供调用方引用。

您不能创建一个

ObjectClass

实例吗？@AmiramKorach我已经按照阿克顿的建议尝试过了，但仍然出错。请找出阿克顿回答中的错误。这只是一个观察，但你真的很想被黑客攻击。您的SQL只接受用户键入的任何内容并将其串在一起：使您面临SQL注入攻击。通过使用SQL参数来解决这个问题<代码>与“WebApplicationvc.ServiceReference1.Service1Client.SetDataUsingDataContract（WebApplicationvc.ServiceReference1.ObjectClass）”匹配的最佳重载方法'具有一些无效参数和

参数'1'：无法从'WebApplicationvc.ObjectClass'转换为'WebApplicationvc.servicerence1.ObjectClass'

您可能在客户端中定义了两次

ObjectClass

。一个是您自己编写的，另一个是通过添加服务引用生成的。@PavanVParekh引用生成的客户端中的ObjectClass版本（WebApplicationvc.ServiceReference1.ObjectClass）。如果已重复该定义，请将其从WebApplication中删除。您可以有两个名称相同的类，但在内部，即使它们共享相同的成员，它们仍然是不同的。@akton和@AmiramKorach谢谢您从web应用程序中删除重复的对象类是的，但现在我从

Service1Client srv=new Service1Client（）中得到以下错误运行时：运行时错误是无法加载协定“ServiceReference1.IService1”的终结点配置节，因为找到了该协定的多个终结点配置。请按名称指明首选端点配置节。@Amiram Korach我有检查配置文件。我的Appconfig文件两个端点（1是默认值，2是mex）请看我的问题，我已经添加了Appconfig代码。
