如何用C#得到本机上Excel的版本呢？
如题，我想首先判定本机是否已经安装Excel，如果安装了，然后得到Excel的版本号，请高手支招，谢了。 --------------------编程问答-------------------- //判断本机是否安装Excel文件方法private bool codeboolisExcelInstalled()
{
Type type = Type.GetTypeFromProgID("Excel.Application");
return type != null;
}
/// <summary>
/// Self_Variable:查询注册表某个键值是否存在
/// </summary>
/// <returns></returns>
public bool ExistsRegedit()
{
bool ifused = false;
RegistryKey rk = Registry.LocalMachine;
RegistryKey akey = rk.OpenSubKey(@"SOFTWARE\\Microsoft\\Office\\11.0\\Word\\InstallRoot\\");
RegistryKey akeytwo = rk.OpenSubKey(@"SOFTWARE\\Microsoft\\Office\\12.0\\Word\\InstallRoot\\");
//检查本机是否安装Office2003
if (akey != null)
{
string file03 = akey.GetValue("Path").ToString();
if (File.Exists(file03 + "Excel.exe"))
{
ifused = true;
}
}
//检查本机是否安装Office2007
if (akeytwo != null)
{
string file07 = akeytwo.GetValue("Path").ToString();
if (File.Exists(file07 + "Excel.exe"))
{
ifused = true;
}
}
return ifused;

在桌面右键创建看是否可以创建.xls或者.xlsx的文件 --------------------编程问答-------------------- public static double JongCheckExcelVer()

我觉得真的很强大~~
补充：.NET技术 , C#
