-- C#操作注册表建立文件关联
提供两个方法 建立个是删除文件关联 使用方式 ViewScreen.ViewControl.ViewDraw.SaveReg(@"C:\IVRDesigner.exe", ".vrd"); 在程序中获得参数关联参数 Environment.CommandLine 方法 需要引用using Microsoft.Win32; /// <summary>
/// 设置文件关联
/// </summary>
/// <param name="p_Filename">程序的名称</param>
/// <param name="p_FileTypeName">扩展名 .VRD </param>
public static void SaveReg(string p_Filename,string p_FileTypeName)
{
RegistryKey _RegKey = Registry.ClassesRoot.OpenSubKey("", true); //打开注册表 RegistryKey _VRPkey = _RegKey.OpenSubKey(p_FileTypeName);
if (_VRPkey != null) _RegKey.DeleteSubKey(p_FileTypeName, true);
_RegKey.CreateSubKey(p_FileTypeName);
_VRPkey = _RegKey.OpenSubKey(p_FileTypeName, true);
_VRPkey.SetValue("", "Exec"); _VRPkey = _RegKey.OpenSubKey("Exec", true);
if (_VRPkey != null) _RegKey.DeleteSubKeyTree("Exec"); //如果等于空 就删除注册表DSKJIVR _RegKey.CreateSubKey("Exec");
_VRPkey = _RegKey.OpenSubKey("Exec", true);
_VRPkey.CreateSubKey("shell");
_VRPkey = _VRPkey.OpenSubKey("shell", true); //写入必须路径
_VRPkey.CreateSubKey("open");
_VRPkey = _VRPkey.OpenSubKey("open", true);
_VRPkey.CreateSubKey("command");
_VRPkey = _VRPkey.OpenSubKey("command", true);
string _PathString = "\"" + p_Filename + "\" \"%1\"";
_VRPkey.SetValue("", _PathString); //写入数据
}
/// <summary>
/// 删除文件关联
/// </summary>
/// <param name="p_FileTypeName">扩展名 .VRD </param>
public static void DelReg(string p_FileTypeName)
{
RegistryKey _Regkey = Registry.ClassesRoot.OpenSubKey("", true); RegistryKey _VRPkey = _Regkey.OpenSubKey(p_FileTypeName);
if (_VRPkey != null) _Regkey.DeleteSubKey(p_FileTypeName, true);
if (_VRPkey != null) _Regkey.DeleteSubKeyTree("Exec"); }
