ToolTask.EnvironmentOverride Property

Note: This API is now obsolete.

Gets a set of environment variable name-value pairs. Designed to be overridden in a custom task class (derived from ToolTask) to return a set of new or altered environment variables to create the execution context of the associated tool.

MSBuild is now included in Visual Studio instead of the .NET Framework. You can use MSBuild 12.0 side-by-side with versions previously deployed with the .NET Framework.For more information, see What's New in MSBuild 12.0.

Property Value

Type: StringDictionary
Returns a set of environment variables. Each dictionary key is the name of the environment variable to override and the dictionary value is the value to set for that environment variable. The default implementation of EnvironmentOverride returns null.

Remarks

The ExecuteTool method passes these environment variables to the StartInfo of the process in which the tool executes. Any environment variables not included in the EnvironmentOverride dictionary are inherited from the process in which the ExecuteTool method executes.

Examples

using System;
using Microsoft.Build.Utilities;
using System.Collections.Specialized;
 
/// <summary>
/// CustomToolTask overrides the EnvironmentOverride property of ToolTask to add a directory
/// to the Path environment variable of the process being executed
/// </summary>
abstract class CustomToolTask : ToolTask
{
      protected override StringDictionary EnvironmentOverride
      {
            get
            {
                  string newPath = Environment.GetEnvironmentVariable("Path", EnvironmentVariableTarget.Process) + @";C:\MyDirectory";
                  StringDictionary result = new StringDictionary();
                  result.Add("Path", newPath);
                  return result;
            }
      }
}
