问题描述
我尝试了几种类型的示例,从另一个带有参数的.exe文件中调用一个.exe文件,其参数为
运行 Web服务,但有时会得到 500 –内部服务器错误异常。
i have tried with several type of examples to call a .exe file from another .exe file with parameters to
run a 'web service',but i am getting some times '500 – Internal Server Error exception'.
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:当我调用此服务时,我必须使用不同的参数运行该服务8次来自8个批处理文件的第二个.EXE文件,然后没有问题。
// NOTE-- i have to run this service 8 times with different parameters, when i call this second .EXE from 8 batch files one by one, then no issue.
现在我正在尝试从我的批处理文件的第一个.exe实例逐个运行此服务。在按钮单击事件中,那么当第一个事件完成第二个事件开始时,我得到500错误。
now i am trying to Run this service from my First .Exe instad of Batch file one by one in button click events , then i am getting the 500 error when first event complete second event start.
我做错了,请给我一些建议。
what i am doing wrong,Please give me some suggestions.
推荐答案
替换此行:
startInfo.FileName = @"C:\WebserviceClient.exe";
具有以下行:
ThreadPool.QueueUserWorkItem(delegate { Process.Start("C:\\WebserviceClient.exe"); });
另一种方法如下:
public static void TestCommands()
{
var command = "WebserviceClient.exe";
ExecuteCommand(command, 5000);
var command = "WebserviceClient2.exe";
ExecuteCommand(command, 5000);
}
public static int ExecuteCommand(string command, int timeout)
{
var processInfo = new ProcessStartInfo(command)
{
CreateNoWindow = true,
UseShellExecute = false,
WorkingDirectory = @"C:\\",
};
var process = Process.Start(processInfo);
process.WaitForExit(timeout);
var exitCode = process.ExitCode;
process.Close();
return exitCode;
}
