Can you please show me with an example?

推荐答案

您可以看看here为一个例子，但主要是它可以这样做：

You can look here for an example, but mainly it can be done like this:

internal string GetSystemDefaultBrowser() { string name = string.Empty; RegistryKey regKey = null; try { //set the registry key we want to open regKey = Registry.ClassesRoot.OpenSubKey("HTTP\\shell\\open\\command", false); //get rid of the enclosing quotes name = regKey.GetValue(null).ToString().ToLower().Replace("" + (char)34, ""); //check to see if the value ends with .exe (this way we can remove any command line arguments) if (!name.EndsWith("exe")) //get rid of all command line arguments (anything after the .exe must go) name = name.Substring(0, name.LastIndexOf(".exe") + 4); } catch (Exception ex) { name = string.Format("ERROR: An exception of type: {0} occurred in method: {1} in the following module: {2}", ex.GetType(), ex.TargetSite, this.GetType()); } finally { //check and see if the key is still open, if so //then close it if (regKey != null) regKey.Close(); } //return the value return name; }
