流程不会运行 [英] Process won't run

问题描述

我正在构建一个Web应用程序来收集用户信息，然后启动一个

过程来计算结果。该过程是第三方可执行文件。我

无法启动流程。这段代码有问题吗？


公共重载共享函数StartApplication（ByVal fileName As String，

ByVal myPath As String）作为流程

尝试

Dim WtDistrib作为新流程

WtDistrib.StartInfo.Verb ="执行"

WtDistrib.StartInfo.CreateNoWindow =真实

Dim SI As New

ProcessStartInfo（" C：\ Inetpub \wwwroot \Uniformity\Pr ocessStuff \WtDistrib.exe"）

WtDistrib.Start（SI）

WtDistrib.WaitForExit（）

Console.WriteLine（WtDistrib.ExitCode）

控制台。 WriteLine（WtDistrib.exe已关闭：&

WtDistrib.ExitTime&"。

WtDistrib.Close（）


Catch e As Exception

Debug.Write（" Error：" + e.Message）

Console.WriteLine（"引发了以下异常：+

e.Message

结束尝试


结束功能

I am building a web application to gather user information then launch a
process to calculate results. The process is a 3rd Party executable. I
cannot get the process to start. Is there a problem with this code?

Public Overloads Shared Function StartApplication(ByVal fileName As String,
ByVal myPath As String) As Process
Try
Dim WtDistrib As New Process
WtDistrib.StartInfo.Verb = "Execute"
WtDistrib.StartInfo.CreateNoWindow = True
Dim SI As New
ProcessStartInfo("C:\Inetpub\wwwroot\Uniformity\Pr ocessStuff\WtDistrib.exe")
WtDistrib.Start(SI)
WtDistrib.WaitForExit()
Console.WriteLine(WtDistrib.ExitCode)
Console.WriteLine("WtDistrib.exe was closed at: " &
WtDistrib.ExitTime & ".")
WtDistrib.Close()

Catch e As Exception
Debug.Write("Error: " + e.Message)
Console.WriteLine("The following exception was raised: " +
e.Message)
End Try

End Function

推荐答案

不要在一个'应该在ASP.NET中工作的方法'中使用Console.WriteLine

网络应用。

如果需要，可以使用System.Diagnostics.Debug.WriteLine。

Don''t use Console.WriteLine in a method that''s supposed to work in an ASP.NET

You could use System.Diagnostics.Debug.WriteLine if you want.

Caroline，

为什么这种方法的返回类型是处理？这没有意义。

不应该有一个返回类型（或者如果有的话，或许是b / b
成功的布尔值，我想）。 />

您是否在调试器中完成了代码？当你这样做会发生什么？

Caroline,
Why is the return type from this method "Process"? That doesn''t make sense.
There shouldn''t be a return type (or if there is , perhaps boolean for
success, I suppose).

Have you stepped through your code in the debugger? What happens when you do?

我删除了Process返回类型。


当我单步执行时，会抛出异常


WtDistrib.WaitForExit（）


没有线程与此进程相关联。


我发布的示例只是我尝试过的几个中的一个。这是我的第一个asp.net应用程序的
。


" Peter Bromberg [C＃MVP]"写道：

I dropped the Process return type.

When I step through, an exception is thrown at

WtDistrib.WaitForExit()

"No thread is associated with this process."

The example I posted is only one of several that I have tried. This is my
first asp.net application.
