C#获取IDL路径安装路径

在基于ENVI的二次开发中，要提供idl.dll  的路径。获取该路径需要获取idl的安装目录，一般在ENVI安装的根目录下。为了获取ENVI的安装目录，读取注册表信息。

  public static string IDLBinPath
{

get
{
using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Uninstall", false))
{
if (key != null)//判断对象存在
{
foreach (string keyName in key.GetSubKeyNames())//遍历子项名称的字符串数组
{
using (RegistryKey key2 = key.OpenSubKey(keyName, false))//遍历子项节点
{
if (key2 != null)
{
string softwareName = key2.GetValue("DisplayName", "").ToString();//获取软件名
string installLocation = key2.GetValue("InstallLocation", "").ToString();//获取安装路径
if (!string.IsNullOrEmpty(installLocation))
{
if (softwareName == "ENVI 4.7")
{
IDLpathrout = installLocation + "IDL71\\bin\\bin.x86\\idl.dll";
}

}
}
}
}
}
}
return IDLpathrout;

}
