在服务器中保存iamge（godaddy） [英] saving iamge in server(godaddy)

问题描述

大家好，



i我正在使用此代码将数据保存在服务器（godaddy）中，但它没有将图像保存在我的应用程序的文件夹中，所以任何人都可以提供帮助请，

 [WebMethod] 
  public   static   string  SaveImageData（ string   value ， string  remaining_data）
 {
  string  fetchedData =  value  .Substring（ value  .IndexOf（' ，'）+  1 ）; 
  string  str_ins_result =  ; 
  //   string strpath =E：\\Reconciliation_Files \\Recon_Files \\ + voID.Substring（2,2）+\\+ voID.Substring（4,2）+\\+ voID;  
  string  strpath =  〜\\eAHD; 
 
 尝试 
 {
  string  [] methodDetails = fetchedData.Split（' ，'）; 
 
  string  strID_Type_fileName = methodDetails [methodDetails.Length  -   1 ]; 
  string  extension = strID_Type_fileName.Substring（strID_Type_fileName.LastIndexOf（' 。'）+  1 ）; 
 
  string  fileContent = fetchedData.Substring（ 0 ，fetchedData.LastIndexOf（< span class =code-string>' ，'））; 
 
  byte  [] data = Convert.FromBase64String（fileContent）; 
 MemoryStream ms =  new  MemoryStream（data）; 
 
 
  if （！Directory.Exists（strpath））
 {
 Directory.CreateDirectory（strpath） ）; 
} 
 
  //  实例指向 $的文件流b $ b  //  存储文件夹，使用原始文件名 
  //  命名生成的文件 
 
 FileStream fs =  new  FileStream（strpath +   \\ + strID_Type_fileName，FileMode.Create ）; 
 
  string  name_path = fs.Name.ToString（）; 
 
 str_ins_result = save_school_data（name_path，remaining_data）; 
  //  写入包含原始内容的内存流 
  //  文件作为文件流的字节数组 
 
 尝试 
 {
 ms.WriteTo（fs）; 
 ms.Close（）; 
 fs.Close（）; 
 fs.Dispose（）; 
 
  return  str_ins_result; 
} 
  catch （Exception ex_attachSave）
 {
  return   保存文件时引发异常，异常为： + ex_attachSave.Message; 
} 
} 
  catch （Exception exp）
 {
  //   Response.Write（exp.ToString（））;  
  return   文件上传时引发异常，异常为： + exp.Message; 
} 
} 

解决方案

尝试更改strpath：

  string  strpath =  〜\\\ \\ eAHD; 

To：

  string  strpath = Server.MapPath（ 〜\\\\\\\\\ ）; 

' 〜'是我的网站的根目录的IIS引用，并不直接适用于文件IO方法。

我还建议您使用Path.Combine而不是字符串连接：

 FileStream fs =  new  FileStream（Path.Combine（strpath，strID_Type_fileName），FileMode.Create）; 

hi everyone,

i am using this code to save data in server(godaddy) but it is not saving image in my folder of this application so anyone can help me please,

[WebMethod]
   public static string SaveImageData(string value, string remain_data)
   {
       string fetchedData = value.Substring(value.IndexOf(',') + 1);
       string str_ins_result = "";
       //string strpath = "E:\\Reconciliation_Files\\Recon_Files\\" + voID.Substring(2, 2) + "\\" + voID.Substring(4, 2) + "\\" + voID;
       string strpath = "~\\eAHD";

       try
       {
           string[] methodDetails = fetchedData.Split(',');

           string strID_Type_fileName = methodDetails[methodDetails.Length - 1];
           string extension = strID_Type_fileName.Substring(strID_Type_fileName.LastIndexOf('.') + 1);

           string fileContent = fetchedData.Substring(0, fetchedData.LastIndexOf(','));

           byte[] data = Convert.FromBase64String(fileContent);
           MemoryStream ms = new MemoryStream(data);


           if (!Directory.Exists(strpath))
           {
               Directory.CreateDirectory(strpath);
           }

           // instance a filestream pointing to the
           // storage folder, use the original file name
           // to name the resulting file

           FileStream fs = new FileStream(strpath + "\\" + strID_Type_fileName, FileMode.Create);

           string name_path = fs.Name.ToString();

           str_ins_result = save_school_data(name_path, remain_data);
           // write the memory stream containing the original
           // file as a byte array to the filestream

           try
           {
               ms.WriteTo(fs);
               ms.Close();
               fs.Close();
               fs.Dispose();

               return str_ins_result;
           }
           catch (Exception ex_attachSave)
           {
               return "Exception raised while file saving, Exception is : " + ex_attachSave.Message;
           }
       }
       catch (Exception exp)
       {
           //Response.Write(exp.ToString());
           return "Exception raised while file uploading, Exception is : " + exp.Message;
       }
   }

解决方案

Try changing strpath:

string strpath = "~\\eAHD";

To:

string strpath = Server.MapPath("~\\eAHD");

'~' is an IIS reference for "root of my website" and isn't directly applicable to file IO methods.
I'd also suggest that you use Path.Combine instead of string concatenation:

FileStream fs = new FileStream(Path.Combine(strpath, strID_Type_fileName), FileMode.Create);
