C#修改系统环境变量，调用批处理bat

一、设置环境变量

public void SetPath(string pathValue)

        {

            string pathlist;

            pathlist = Environment.GetEnvironmentVariable("PATH", EnvironmentVariableTarget.Machine);

            string[] list = pathlist.Split(';');

            bool isPathExist = false;

            foreach (string item in list)

            {

                if (item == pathValue)

                    isPathExist = true;

            }

            if (!isPathExist)

            {

                Environment.SetEnvironmentVariable("PATH", pathlist + ";" + pathValue, EnvironmentVariableTarget.Machine);

            }

        }

二、程序调用批处理

                Process proc = new Process();

                proc.StartInfo.WorkingDirectory = Application.StartupPath;

                proc.StartInfo.FileName = "service install.bat";

                proc.StartInfo.Arguments = String.Format("10");

                proc.StartInfo.CreateNoWindow = true;

                proc.Start();

                proc.WaitForExit();

                MessageBox.Show("Create Success!");
