public:
property bool UseShellExecute { bool get(); void set(bool value); };
public bool UseShellExecute { get; set; }
member this.UseShellExecute : bool with get, set
Public Property UseShellExecute As Boolean
Property Value
true
if the shell should be used when starting the process; false
if the process should be created directly from the executable file. The default is true
on .NET Framework apps and false
on .NET Core apps.
Exceptions
An attempt to set the value to true
on Universal Windows Platform (UWP) apps occurs.
Examples
// Run "cl.exe /cld stdstr.cpp /link /out:sample.exe". UseShellExecute is false because we're specifying
// an executable directly and in this case depending on it being in a PATH folder. By setting
// RedirectStandardOutput to true, the output of cl.exe is directed to the Process.StandardOutput stream
// which is then displayed in this console window directly.
Process^ compiler = gcnew Process;
compiler->StartInfo->FileName = "cl.exe";
compiler->StartInfo->Arguments = "/clr stdstr.cpp /link /out:sample.exe";
compiler->StartInfo->UseShellExecute = false;
compiler->StartInfo->RedirectStandardOutput = true;
compiler->Start();
Console::WriteLine( compiler->StandardOutput->ReadToEnd() );
compiler->WaitForExit();
// Run "csc.exe /r:System.dll /out:sample.exe stdstr.cs". UseShellExecute is false because we're specifying
// an executable directly and in this case depending on it being in a PATH folder. By setting
// RedirectStandardOutput to true, the output of csc.exe is directed to the Process.StandardOutput stream
// which is then displayed in this console window directly.
using (Process compiler = new Process())

compiler.StartInfo.FileName = "csc.exe";

compiler.StartInfo.UseShellExecute = false;
compiler.StartInfo.RedirectStandardOutput = true;
compiler.Start();
Console.WriteLine(compiler.StandardOutput.ReadToEnd());
compiler.WaitForExit();
}
' Run "vbc.exe /reference:Microsoft.VisualBasic.dll /out:sample.exe stdstr.vb". UseShellExecute is False
' because we're specifying an executable directly and in this case depending on it being in a PATH folder.
' By setting RedirectStandardOutput to True, the output of csc.exe is directed to the Process.StandardOutput
