1：把patran的安裝路徑添加到系統環境變量的path屬性下；

2：在你的批處理里面改為如下格式，patran完整路徑（如c:\MSC.software\········patran.exe)+ "-sfp patran.ses"，也就是下面這種情況試下“c:\MSC.software\········patran.exe -sfp patran.ses -b -ans yes”

vb.net中用shell調用外部exe一直報"未找到文件"的錯誤,但是路徑確實是對的

一般情況下寧可相信計算機也不要太相信自己。

給你個測試的方法，你可以使用File.Create在你上述認為正確的路徑創建一個文件試試，看是否創建到你想要的地方了。

vb.net shell

Shell恐怕不行·

給你個現成的：

Sub _CMD(ByVal Data As String)

Try

Dim p As New Process()‘用Process就可以

p.StartInfo.FileName = "cmd.exe"

p.StartInfo.UseShellExecute = False

p.StartInfo.RedirectStandardInput = True

p.StartInfo.RedirectStandardOutput = True

p.StartInfo.RedirectStandardError = True

p.StartInfo.CreateNoWindow = True

p.Start()

Application.DoEvents()

p.StandardInput.WriteLine(Data)’這個Data就是cmd命令

p.StandardInput.WriteLine("Exit")‘這個是退出語句

Dim strRst As String = p.StandardOutput.ReadToEnd()’執行完語句后取得顯示內容.

p.Close()

Catch ex As Exception

End Try

‘之后就是你自己的代碼了...

End Sub

VB.net中的shell在C#中怎么寫

下面是例子，或許對你有用：

using???System;???

using???System.Diagnostics;???

using???System.ComponentModel;???

namespace???MyProcessSample???

{???

///???summary???

///???Shell???for???the???sample.???

///???/summary???

public???class???MyProcess???

{???

//???These???are???the???Win32???error???code???for???file???not???found???or???access???denied.???

const???int???ERROR_FILE_NOT_FOUND???=2;???

const???int???ERROR_ACCESS_DENIED???=???5;???

///???summary???

///???Prints???a???file???with???a???.doc???extension.???

///???/summary???

public???void???PrintDoc()???

{???

Process???myProcess???=???new???Process();???

try???

{???

//???Get???the???path???that???stores???user???documents.???

string???myDocumentsPath???=?????

Environment.GetFolderPath(Environment.SpecialFolder.Personal);???

myProcess.StartInfo.FileName???=???myDocumentsPath???+???"\\MyFile.doc";?????

myProcess.StartInfo.Verb???=???"Print";???

myProcess.StartInfo.CreateNoWindow???=???true;???

myProcess.Start();???

}???

catch???(Win32Exception???e)???

{???

if(e.NativeErrorCode???==???ERROR_FILE_NOT_FOUND)???

{???

Console.WriteLine(e.Message???+???".???Check???the???path.");???

}?????

else???if???(e.NativeErrorCode???==???ERROR_ACCESS_DENIED)???

{???

//???Note???that???if???your???word???processor???might???generate???exceptions???

//???such???as???this,???which???are???handled???first.???

Console.WriteLine(e.Message???+?????

".???You???do???not???have???permission???to???print???this???file.");???

}???

}???

}???

public???static???void???Main()???

{???

MyProcess???myProcess???=???new???MyProcess();???

myProcess.PrintDoc();???

}???

}???

}
