ProcessStartInfo.Password Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets a secure string containing the user password to use when starting the process.

Namespace: System.Diagnostics
Assembly: System (in system.dll)

public SecureString Password { get; set; }
/** @property */
public SecureString get_Password ()

/** @property */
public void set_Password (SecureString value)

public function get Password () : SecureString

public function set Password (value : SecureString)

Property Value

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

For more information on secure strings, 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.
