Gets or sets a value indicating whether to use the operating system shell to start the process.

Espacio de nombres:   System.Diagnostics
Ensamblado:  System (en System.dll)

member UseShellExecute : bool with get, set

Valor de propiedad

Type: System.Boolean

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.

Setting this property to false enables you to redirect input, output, and error streams.


   P:System.Diagnostics.ProcessStartInfo.UseShellExecute must be false if the P:System.Diagnostics.ProcessStartInfo.UserName property is not null or an empty string, or an T:System.InvalidOperationException will be thrown when the M:System.Diagnostics.Process.Start(System.Diagnostics.ProcessStartInfo) method is called.

When you use the operating system shell to start processes, you can start any document (which is any registered file type associated with an executable that has a default open action) and perform operations on the file, such as printing, by using the T:System.Diagnostics.Process object. When P:System.Diagnostics.ProcessStartInfo.UseShellExecute is false, you can start only executables by using the T:System.Diagnostics.Process object.


UseShellExecute must be true if you set the ErrorDialog property to true.

The P:System.Diagnostics.ProcessStartInfo.WorkingDirectory property behaves differently depending on the value of the P:System.Diagnostics.ProcessStartInfo.UseShellExecute property. When P:System.Diagnostics.ProcessStartInfo.UseShellExecute is true, the P:System.Diagnostics.ProcessStartInfo.WorkingDirectory property specifies the location of the executable. If P:System.Diagnostics.ProcessStartInfo.WorkingDirectory is an empty string, it is assumed that the current directory contains the executable.

When P:System.Diagnostics.ProcessStartInfo.UseShellExecute is false, the P:System.Diagnostics.ProcessStartInfo.WorkingDirectory property is not used to find the executable. Instead, it is used only by the process that is started and has meaning only within the context of the new process. When P:System.Diagnostics.ProcessStartInfo.UseShellExecute is false, the P:System.Diagnostics.ProcessStartInfo.FileName property can be either a fully qualified path to the executable, or a simple executable name that the system will attempt to find within folders specified by the PATH environment variable.
