您可以使用Win32Exception并使用其NativeErrorCode属性对其进行适当处理。
// http://support.microsoft.com/kb/186550const int ERROR_FILE_NOT_FOUND = 2;const int ERROR_ACCESS_DENIED = 5;const int ERROR_NO_APP_ASSOCIATED = 1155;void OpenFile(string filePath){ Process process = new Process(); try { // Calls native application registered for the file type // This may throw native exception process.StartInfo.FileName = filePath; process.StartInfo.Verb = "Open"; process.StartInfo.CreateNoWindow = true; process.Start(); } catch (Win32Exception e) { if (e.NativeErrorCode == ERROR_FILE_NOT_FOUND || e.NativeErrorCode == ERROR_ACCESS_DENIED || e.NativeErrorCode == ERROR_NO_APP_ASSOCIATED) { MessageBox.Show(this, e.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); } }}
