  Can I read file using System.IO namespace? Can I use BinaryReader class and FileStream to read ?

   FileStream fs = new FileStream(Server.MapPath("../Images/Image Not Available.jpg"), FileMode.Open, FileAccess.Read);
                      BinaryReader br = new BinaryReader(fs);
  
                      ds.Tables[0].Rows[0]["DocImage"] = br.ReadBytes(br.BaseStream.Length);
                      br = null;
                      fs.Close();
                      fs = null;

  but the line  ds.Tables[0].Rows[0]["DocImage"] = br.ReadBytes(br.BaseStream.Length); is throwing error i.e.

  Error    20    The best overloaded method match for 'System.IO.BinaryReader.ReadBytes(int)' has some invalid arguments    E:\Joel Data\PipeTracking_GI\PipeTracking_GI\MainCtrls\ctrlReportOffBargeInventory.ascx.cs    71    56    PipeTracking_GI

  Error    21    Argument '1': cannot convert from 'long' to 'int'    E:\Joel Data\PipeTracking_GI\PipeTracking_GI\MainCtrls\ctrlReportOffBargeInventory.ascx.cs    71    69    PipeTracking_GI
  

  
  why this is happening and whats the solution of it ?

  br.ReadBytes(br.BaseStream.Length);
  

   

  Hi azharrah,

  Please check the method of ReadBytes, this method should be work with a int type parameter, but br.BaseStream.Length is a long type!

  So please convert br.BaseStream.Length to int type to solve you problem.

  Hope it helps,

  Hong Gang
