如何使用此C＃代码创建子例程？

Question

我有以下的C＃代码，我已经在我的代码中重新使用了大约20次。我无法弄清楚如何使它成为一个子程序，这将允许我重新使用它的B/C类型的对象每次都基于不同的类。

该代码的目的是发送一个HTTP请求，收集JSON响应，然后将JSON序列化（使用DataContract）到一个类中以用于其他区域。

这里就是我的了：这一特定用途

public static ResponseAttachmentIds MakeRequestAttachmentId(string requestUrl, string strToken) 
    { 
     try 
     { 
      HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest; 
      request.Headers["Authorization"] = "OAuth " + strToken; 
      using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) 
      { 
       if (response.StatusCode != HttpStatusCode.OK) 
        throw new Exception(String.Format(
        "Server error (HTTP {0}: {1}).", 
        response.StatusCode, 
        response.StatusDescription)); 
       DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(ResponseAttachmentIds)); 
       object objResponse = jsonSerializer.ReadObject(response.GetResponseStream()); 
       ResponseAttachmentIds jsonResponse = objResponse as ResponseAttachmentIds; 
       response.Close(); 
       return jsonResponse; 
      } 
     } 
     catch (Exception e) 
     { 
      System.Windows.Forms.MessageBox.Show(e.Message); 
      return null; 
     } 

    } 

的DataContract类：

public class ResponseAttachmentIds 
{ 
    [DataMember(Name = "done")] 
    public bool attachmentIds_done; 
    [DataMember(Name = "records")] 
    public List<ResponseAttachmentId> attachmentIds_records; 
} 
[DataContract] 
public class ResponseAttachmentId 
{ 
    [DataMember(Name = "Id")] 
    public string attachmentId_strId { get; set; } 
    [DataMember(Name = "Image_Attachment_Id__c")] 
    public string attachmentId_strAttachmentId { get; set; } 
} 

的问题是，我也有这个相同的设置约20个不同的类如ResponseImages,ResponseProperties,ResponseProperty等

任何帮助吗？

我相信你想要的是一个通用的方法，例如：

public static T MakeRequestAttachmentId<T>(string requestUrl, string strToken) where T : class 
    { 
     try 
     { 
      HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest; 
      request.Headers["Authorization"] = "OAuth " + strToken; 
      using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) 
      { 
       if (response.StatusCode != HttpStatusCode.OK) 
        throw new Exception(String.Format(
        "Server error (HTTP {0}: {1}).", 
        response.StatusCode, 
        response.StatusDescription)); 
       DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(T)); 
       object objResponse = jsonSerializer.ReadObject(response.GetResponseStream()); 
       var jsonResponse = (T)objResponse; 
       response.Close(); 
       return jsonResponse; 
      } 
     } 
     catch (Exception e) 
     { 
      System.Windows.Forms.MessageBox.Show(e.Message); 
      return default(T); 
     } 

    } 

而且你可以把它作为这样的：

MakeRequestAttachmentId<ResponseAttachmentIds>("", "");

我会改变使用泛型方法。像...

public static T MakeResponseObject<T>(string requestUrl, string strToken) 
{ 
    try 
    { 
     HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest; 
     request.Headers["Authorization"] = "OAuth " + strToken; 
     using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) 
     { 
      if (response.StatusCode != HttpStatusCode.OK) 
       throw new Exception(String.Format(
       "Server error (HTTP {0}: {1}).", 
       response.StatusCode, 
       response.StatusDescription)); 
      DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(T)); 
      object objResponse = jsonSerializer.ReadObject(response.GetResponseStream()); 
      var jsonResponse = objResponse as T; 
      response.Close(); 
      return jsonResponse; 
     } 
    } 
    catch (Exception e) 
    { 
     System.Windows.Forms.MessageBox.Show(e.Message); 
     return null; 
    } 
}
