问题描述

如何用流读取System.Drawing.Image数组

此代码不起作用：

 < span class =code-keyword> int  i =  0 ; 
 Image [] image =  new 图片[ 100 ]; 
  while （reader.Read（））
 {
  string  filePath =（ string ）reader [  Path]; 
  byte  [] transactionContext =（ byte  []）reader [  TransactionContext]; 
 SqlFileStream sqlFileStream =  new  SqlFileStream（filePath，transactionContext，FileAccess.Read）; 
  byte  [] data =  new   byte [Convert.ToInt32(sqlFileStream.Length）]; 
 sqlFileStream2.Read（data， 0 ，Convert.ToInt32（sqlFileStream.Length））; 
 image [i] = System.Drawing.Image.FromStream（sqlFileStream， true ， true  ）; 
  //   sqlFileStream.Close（）;  
 i ++; 
 
}

        string filePath = (string)reader["Path"];
        byte[] transactionContext = (byte[])reader["TransactionContext"];
        SqlFileStream sqlFileStream = new SqlFileStream(filePath, transactionContext, FileAccess.Read);
        byte[] data = new byte[Convert.ToInt32(sqlFileStream.Length)];
        sqlFileStream2.Read(data, 0, Convert.ToInt32(sqlFileStream.Length));
        image[i] = System.Drawing.Image.FromStream(sqlFileStream, true, true);
        //sqlFileStream.Close();
        i++;

    }
