C# 通过注册表检测是否安装office组件

最近工作中遇到的一些问题,我将都记录在sina博客,成为技术博文,以便日后查阅,当然也欢迎各位网友进行拍砖练习.

代码如下:

publicclass TestOffice
  2     {
  3 public TestOffice()
  4         { }
  5 ///<summary>
  6 /// 检测是否安装office
  7 ///</summary>
  8 ///<param name="str_Version"> 获得并返回安装的office版本</param>
  9 ///<returns></returns>
 10  publicstaticbool IsInstall(outstring str_Version)
 11         {
 12 bool result =false;
 13 string str_OfficePath =string.Empty;
 14 string str_OfficeVersion =string.Empty;
 15             str_Version =string.Empty;
 16 
 17             GetOfficePath(out str_OfficePath, out str_OfficeVersion);
 18 if (!string.IsNullOrEmpty(str_OfficePath)&&!string.IsNullOrEmpty(str_OfficeVersion))
 19             {
 20                 result =true;
 21                 str_Version = str_OfficeVersion;
 22             }
 23 
 24 return result;
 25         }
 26 
 27 ///<summary>
 28 /// 获取并返回当前安装的office版本和安装路径
 29 ///</summary>
 30 ///<param name="str_OfficePath">office的安装路径</param>
 31 ///<param name="str_OfficeVersion">office的安装版本</param>
