推荐答案

public static string getContentType(string extension)
       {
           const string DEFAULT_CONTENT_TYPE = "application/unknown";
           RegistryKey regkey, fileextkey;
           string filecontenttype;
           string fileextension = extension;
           try
           {
               regkey = Registry.ClassesRoot;
               fileextkey = regkey.OpenSubKey(fileextension);
               filecontenttype = fileextkey.GetValue("Content Type", DEFAULT_CONTENT_TYPE).ToString();
               fileextkey = null;
               regkey = null;
           }
           catch
           {
               filecontenttype = DEFAULT_CONTENT_TYPE;
           }
           return filecontenttype;
       }

传递精确的内容类型，例如"pdf，txt，xmlns"

Pass Exact contenttype like "pdf,txt,xmlns"
