 property System::Security::SecureString ^ Password { System::Security::SecureString ^ get(); void set(System::Security::SecureString ^ value); };

Public Property Password As SecureString

Property Value


The user password to use when starting the process.




The WorkingDirectory property must be set if UserName and Password are provided. If the property is not set, the default working directory is %SYSTEMROOT%\system32.


Setting the Domain, UserName, and the Password properties in a ProcessStartInfo object is the recommended practice for starting a process with user credentials.

A SecureString object is like a String object in that it has a text value. However, the value of a SecureString object is automatically encrypted, it can be modified until your application marks it as read-only, and it can be deleted from computer memory by either your application or the .NET Framework garbage collector.

For more information about secure strings and an example of how to obtain a password to set this property, see the SecureString class.


If you provide a value for the Password property, the UseShellExecute property must be false, or an InvalidOperationException will be thrown when the Process.Start(ProcessStartInfo) method is called.
