当出现故障合同时，我在为WCF服务创建客户端时遇到问题。
当我把错误契约，客户端无法实例化时，它只能看到WPCILServiceException对象和WPCILEndResponse对象。
下面是服务的工作代码，没有错误合同：
namespace WcfS001
{
[ServiceContract]
public interface IS001
{
[OperationContract]
WPCILEndResponse GetMasterListDebug(string xml);
[OperationContract]
WPCILEndResponse GetMasterListWpc(S001_WPC_Input input);
}
}
当我使用Windows Form创建客户端时，我创建了一个调用此服务的按钮，如下所示：
private void button1_Click(object sender, EventArgs e)
{
if (!String.IsNullOrEmpty(textBoxInput.Text))
{
S001Service.S001Client clientConnection = new S001Service.S001Client();
try
{
S001Service.WPCILEndResponse response = clientConnection.GetMasterListDebug(textBoxInput.Text);
textBoxCorrId.Text = response._correlationId;
textBoxService.Text = response._service;
}
catch (Exception ex)
{
textBoxEx.Text = ex.Message;
}
}
else
{
MessageBox.Show("Input textbox is empty!");
}
}
我可以毫无问题地看到“S001Service.S001Client”。
但是，当我添加如下的故障合同时，“S001Service.S001Client”不再存在，即使在对象浏览器中也看不到它。我只能看到异常对象类型！
namespace WcfS001
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IS001" in both code and config file together.
[ServiceContract]
public interface IS001
{
[OperationContract]
[FaultContract(typeof(WPCILServiceException))]
WPCILEndResponse GetMasterListDebug(string xml);
[OperationContract]
[FaultContract(typeof(WPCILServiceException))]
WPCILEndResponse GetMasterListWpc(S001_WPC_Input input);
}
}
所以下面的代码不再起作用了
private void button1_Click(object sender, EventArgs e)
{
if (!String.IsNullOrEmpty(textBoxInput.Text))
{
**//S001Client doesn't exists anymore - why???
S001Service.S001Client clientConnection = new S001Service.S001Client();**
try
{
S001Service.WPCILEndResponse response = clientConnection.GetMasterListDebug(textBoxInput.Text);
textBoxCorrId.Text = response._correlationId;
textBoxService.Text = response._service;
}
catch (Exception ex)
{
textBoxEx.Text = ex.Message;
}
}
else
{
MessageBox.Show("Input textbox is empty!");
}
}
好像我的客户端无法读取正确的WSDL（附在下面）：

我从来没有使用过错合同......我错过了什么吗？
谢谢
