在pda上怎样打开网页或者调用其他可程序（主要是指可执行文件）的公共类

using System;
using System.Runtime.InteropServices;

namespace BaseStationPDA
{
 /// <summary>
 /// Summary description for Invoke.
 /// </summary>
 public class Invoke
 {
  public Invoke()
  {
   //
   // TODO: Add constructor logic here
   //
  }
  [DllImport("coredll.Dll")]
  private static extern int CreateProcess(string strImageName, string strCmdLine, IntPtr pProcessAttributes, IntPtr pThreadAttributes , int bInheritsHandle, int dwCreationFlags, IntPtr pEnvironment, IntPtr pCurrentDir, Byte[] bArray, ProcessInfo oProc);

  public  void ShowWebSite(string path)
  {
   ProcessInfo pi = new ProcessInfo();
   CreateProcess("iexplore.exe", path, IntPtr.Zero, IntPtr.Zero, 0, 0, IntPtr.Zero, IntPtr.Zero, new Byte[128], pi);
  }

  public  void StartIE( )
  {

   ProcessInfo pi = new ProcessInfo();
   CreateProcess("iexplore.exe", "", IntPtr.Zero, IntPtr.Zero, 0, 0, IntPtr.Zero, IntPtr.Zero, new Byte[128], pi);
  }

  public  void StartPrograme(string name)
  {

   ProcessInfo pi = new ProcessInfo();
   CreateProcess(name, "", IntPtr.Zero, IntPtr.Zero, 0, 0, IntPtr.Zero, IntPtr.Zero, new Byte[128], pi);
  }
 }
 public class ProcessInfo
 {
  public int Process;
  public int Thread;
  public int ProcessID;
  public int ThreadID;
 }
}

在调用时EXample:

（1）调用可执行文件

private void DataCall()
  {
   string path="\\DataCall.exe";
   FileInfo fileexis=new FileInfo(path);
   if(fileexis.Exists)
   {
    Invoke invoke=new Invoke();
    invoke.StartPrograme(path);
   }
  }

（2）打开网页

private void openid()

{

 if(GetParam.SelBSId=="")
   {
    MessageBox.Show("未发现附近维护点，请点击上面[获取]按钮获取维护点!","系统提示",MessageBoxButtons.OK,MessageBoxIcon.Exclamation,MessageBoxDefaultButton.Button1);
    return;
   }
   if(GetParam.webhost=="")
   {
    MessageBox.Show("请在设置页面设置WEB服务器地址!","系统提示",MessageBoxButtons.OK,MessageBoxIcon.Exclamation,MessageBoxDefaultButton.Button1);
    return;
   }   
   string path="http://"+GetParam.webhost+"/BaseStation/MobilePages/FCheckTempBSEq.aspx?userId="+GetParam.UserID
      +"&password="+GetParam.password+"&BSId="+GetParam.SelBSId+"&companyId="+GetParam.companyId+"&device=pda"
      +"&user="+GetParam.UserID+"&url=FCheckTempBSEq.aspx";
   Invoke invoke=new Invoke();
   invoke.ShowWebSite(path);

}
