Property Value

A StringDictionary that provides environment variables that apply to this process and child processes. The default is a null reference (Nothing in Visual Basic).

Although you cannot set the EnvironmentVariables property, you can modify the StringDictionary returned by the property. For example, the following code adds a TempPath environment variable: myProcess.StartInfo.EnvironmentVariables.Add("TempPath", "C:\\Temp"). You must set the UseShellExecute property to false to start the process after changing the EnvironmentVariables property. If UseShellExecute is true, an InvalidOperationException is thrown when the Start method is called.
