ProcessStartInfo.EnvironmentVariables Property

Gets search paths for files, directories for temporary files, application-specific options, and other similar information.

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

[MonitoringDescriptionAttribute("ProcessEnvironmentVariables")]
public StringDictionary EnvironmentVariables { get; }

Property Value

Type: System.Collections.Specialized.StringDictionary
A string dictionary that provides environment variables that apply to this process and child processes. The default is null.

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.
