C# WCF返回的客户端中的访问对象

我有一个WCF服务，它返回一个类对象。如何在客户端应用程序中访问这些返回值

服务代码：

public ET_ITAM_RequestDetails GetAssociateFreewareRequestDetails(ET_ITAM_RequestDetails objET_ITAM_RequestDetails)
{
    SqlDataReader rdr = null;
    connect.Open();
    SqlCommand cmd = new SqlCommand("ET_ITAM_GetAssociateFreewareRequestDetails", connect);
    cmd.CommandType = CommandType.StoredProcedure;

    while (rdr.Read())
    {
        objET_ITAM_RequestDetails.AssociateID = (string)rdr[0];
        objET_ITAM_RequestDetails.AssetID = (string)rdr[1];
        objET_ITAM_RequestDetails.ETRequestID = (int)rdr[2];
        objET_ITAM_RequestDetails.FreewareName = (string)rdr[3];
        objET_ITAM_RequestDetails.InstallationCommand = (string)rdr[4];
        objET_ITAM_RequestDetails.InstallationArguments = (string)rdr[5];
        objET_ITAM_RequestDetails.VerificationType = (bool)rdr[6];
        objET_ITAM_RequestDetails.VerificationPath = (string)rdr[7];
    }

    return objET_ITAM_RequestDetails;
}

在客户端：

ServiceReference1.ET_ITAM_RequestDetails objItam = new 

ServiceReference1.ET_ITAM_RequestDetails();

// need to get return value.
// if i create another object it not work as expected
obj_service.GetAssociateFreewareRequestDetails(objItam);

---

通过

servicerence1

判断，您似乎已成功地将WCF引用添加到客户端解决方案中。但是，据我所知，您缺少WCF客户端

您没有提供足够的信息来知道将调用什么客户端，但您的代码应该如下所示：

ServiceReference1.ET_ITAM_RequestDetails objItam = new 
    ServiceReference1.ET_ITAM_RequestDetails();

// the service generation will create a WCF client for you, thought I'm not sure what your client's name would be.
objItam = obj_service.GetAssociateFreewareRequestDetails(objItam);

---

再次查看您的代码，我想我看到了您的问题。您确实更新了wcf客户端，但未提供该客户端的代码

obj_service.GetAssociateFreewareRequestDetails(objItam);

您只是调用函数，而不是将其值赋回对象

objItam = obj_service.GetAssociateFreewareRequestDetails(objItam);

我不清楚为什么要新建一个空对象，将它传递到函数中，然后返回它。为什么不直接更新它并在函数中返回它呢

public ET_ITAM_RequestDetails GetAssociateFreewareRequestDetails()
{
    ET_ITAM_RequestDetails objET_ITAM_RequestDetails = new ET_ITAM_RequestDetails();

    SqlDataReader rdr = null;
    connect.Open();
    SqlCommand cmd = new SqlCommand("ET_ITAM_GetAssociateFreewareRequestDetails", connect);
    cmd.CommandType = CommandType.StoredProcedure;

    while (rdr.Read())
    {
        objET_ITAM_RequestDetails.AssociateID = (string)rdr[0];
        objET_ITAM_RequestDetails.AssetID = (string)rdr[1];
        objET_ITAM_RequestDetails.ETRequestID = (int)rdr[2];
        objET_ITAM_RequestDetails.FreewareName = (string)rdr[3];
        objET_ITAM_RequestDetails.InstallationCommand = (string)rdr[4];
        objET_ITAM_RequestDetails.InstallationArguments = (string)rdr[5];
        objET_ITAM_RequestDetails.VerificationType = (bool)rdr[6];
        objET_ITAM_RequestDetails.VerificationPath = (string)rdr[7];
    }

    return objET_ITAM_RequestDetails;
}

如果您的读者不止一行，上述（以及您的原件）当然会（可能）产生意外的结果-只是在您不知道的情况下调用它。

不要对WCF客户端使用

使用
：我已成功地在我的客户端中添加了服务引用，如下所示。ServiceReference1.ETServiceClient对象服务=新的ServiceReference1.ETServiceClient（）；我在客户机中添加了一个ET_ITAM_RequestDetails对象，它是来自我的服务的返回类型。ServiceReference1.ET_ITAM_RequestDetails objItam=新的ServiceReference1.ET_ITAM_RequestDetails（）；
