Question

我正在尝试在给定的时间跨度内从客户端应用程序向我的WCF服务发送消息我想知道的是我的WCF服务被客户击中的次数。

这是一个客户端应用程序：

var messages = new String[1];
messages[0] = "My simple request";
  var client2 = new Operator();
var startTime = DateTime.Now;
var timeoutSpan = TimeSpan.FromMinutes(.06);
var count =0;

while ((DateTime.Now - startTime) <= timeoutSpan)
{
    foreach (string message in messages)
    {
        txtRequest.Text = message;
        sendMessageResult = client.sendMessage("02", txtRequest.Text);
        count++;
    }
}

// this counts how many request I sent 
textBox1.Text = count.ToString();
// this shows the server side count
textBox2.Text = client2.TotalHits().ToString();

这是我的WCF服务应用程序

编辑：

  public byte sendMessage(string strMsgId, string strMessage)
  {
   byte result = 1;

    try
    {
       if (strMsgId == "02") 
       {

        lock (_lock)
                {
                    ++_count;
                }
          // Logging-------
          // Build timestamp string
          var currentDateTime = DateTime.Now;
          string timeStampString = currentDateTime.ToString("yyyy-MM-dd hhmmssfff");

          // Build filename for Inbound messages, concat timestamp and .txt extension.
          string debugFileName = "C:\\Inboundmessage" + " " + timeStampString + ".txt";
          var inboundMessageLog = new StreamWriter(debugFileName, false, System.Text.Encoding.Default);

          // Write to the file:
          inboundMessageLog.WriteLine(DateTime.Now);
          inboundMessageLog.WriteLine("Time = {0}", currentDateTime.ToString("yyyy-MM-dd hh:mm:ss:fff tt"));
          inboundMessageLog.WriteLine("{0}{1}{2}", "Inbound Message:", Environment.NewLine, strMessage);
        inboundMessageLog.WriteLine("{0}{1}", "count:", _count);
          inboundMessageLog.Close();

          // --------------
          result = 0;
      }
}
catch
{
    //Failed
    result = 1;
}
return result;

//这是一个计数方法

   public int TotalHits()
    {
        return _count;
    }

我在日志中看到计数是> 0但是为什么在客户端我在调用TotalHit方法时没有看到更改？

一个问题：你究竟想在这里实现什么目标？

解决方案有两个步骤：步骤1：在IService启用会话

[ServiceContract()]
public interface IService
{
    [OperationContract]
    string SayHello(string toWhom);

    [OperationContract]
    int TotalHits();

}

步骤2：添加ServiceBehavior标记以启用Singleton

[ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)]
public Service: IService
{
    int count;
    object _lock = new object();

    string SayHello(string toWhom)
    {
        lock(_lock) { ++count; }

        return "Hello, " + toWhom;
    }

    int TotalHits()
    {
        return count;
    }
}
