C# 从另一个.exe调用.exe以运行Web服务

我尝试了几种类型的示例，从另一个带有参数的.exe文件调用.exe文件，以 运行“web服务”，但有时我会遇到“500–内部服务器错误异常”

1. code in First .Exe(code for only for one event, i have 8 event like this to run in Button click)    

    dateTimePicker4.CustomFormat = "yyyy-MM-dd";   
            string frodate = dateTimePicker4.Value.Date.ToShortDateString();
            ProcessStartInfo startInfo = new ProcessStartInfo();
            startInfo.FileName = @"C:\WebserviceClient.exe";           // this is the second .EXE file
            startInfo.Arguments = "300000 supplier" + " " + frodate;   // thesse are the 3 parameters
            Process.Start(startInfo);

 2. My second .Exe file receive these parameters and call the Web-Service like below

WebRequest webRequest = WebRequest.Create("http://My Server Path/epos/getproduct.asmx"); // this is web service in another location 
            HttpWebRequest httpRequest = (HttpWebRequest)webRequest;
            httpRequest.Method = "POST";
            httpRequest.ContentType = "text/xml; charset=utf-8";
            httpRequest.Headers.Add("SOAPAction: http://tempuri.org/getCategory");
            httpRequest.ProtocolVersion = HttpVersion.Version11;
            httpRequest.Credentials = CredentialCache.DefaultCredentials;
            Stream requestStream = httpRequest.GetRequestStream();
            //Create Stream and Complete Request             
            StreamWriter streamWriter = new StreamWriter(requestStream, Encoding.ASCII);

        StringBuilder soapRequest = new StringBuilder("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"");
        soapRequest.Append(" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" ");
        soapRequest.Append("xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"><soap:Body>");
        soapRequest.Append("<getCategory xmlns=\"http://tempuri.org/\">");
        soapRequest.Append("<inBranch>" + strParam + "</inBranch>");
        soapRequest.Append("<dir>" + strParamDir + "</dir>");
        soapRequest.Append("<modifyDateFrom>" + strModifyDateFrom + "</modifyDateFrom>");
        soapRequest.Append("<modifyDateTo>" + strModifyDateTo + "</modifyDateTo>");
        soapRequest.Append("</getCategory>");

        soapRequest.Append("</soap:Body></soap:Envelope>");

        streamWriter.Write(soapRequest.ToString());
        streamWriter.Close();
        //Get the Response    
        HttpWebResponse wr = (HttpWebResponse)httpRequest.GetResponse();  // here i am getting the ERROR
        StreamReader srd = new StreamReader(wr.GetResponseStream());
        string resulXmlFromWebService = srd.ReadToEnd();

//注意-我必须使用不同的参数运行此服务8次，当我从8个批处理文件逐个调用第二个.EXE时，没有问题

现在我正在尝试从button click events中的批处理文件的第一个.Exe instad中逐个运行此服务，然后当第一个事件完成第二个事件启动时，我收到500错误

我做错了什么，请给我一些建议。

替换这行：

        startInfo.FileName = @"C:\WebserviceClient.exe";

ThreadPool.QueueUserWorkItem(delegate { Process.Start("C:\\WebserviceClient.exe"); });

这一行：

        startInfo.FileName = @"C:\WebserviceClient.exe";

ThreadPool.QueueUserWorkItem(delegate { Process.Start("C:\\WebserviceClient.exe"); });

另一种方法是：

尝试添加Process.WaitForExit；在您的流程之后。StartstartInfo；哦，是的。毫无疑问，这个过程似乎不是以单个进程结束的，运行了3次。我不太确定，我正在测试我的应用程序，2次得到相同的结果，3次执行。仍在测试中，无论如何感谢您的解决方案。大家好，我的系统运行良好。问题是，当我运行该服务时，所有相关记录都会插入到我的日志表中，但一段时间后，这些记录也会第二次插入，并且会在我的日志表中不断插入重复记录。如何停止重复插入。我建议发布另一个包含详细信息的问题。
