error in Hashtable methods

Question

Hi...
I am using hashtable as below

buffer=new Hashtable();
if (table.Rows.Count > 0)
                    {
                       if (this.buffer.get_Item(this.Flex.Row) == null)
                        {
                            this.buff = (byte[])table.Rows[0]["Picture"];
                            this.buffer.set_Item(this.Flex.Row, this.buff);
                        }
                        this.lblpic.Visible = false;
                        this.buff = (byte[])this.buffer.get_Item(this.Flex.Row);
                        MemoryStream stream = new MemoryStream(this.buff, true);
                        stream.Write(this.buff, 0, this.buff.Length);
                        Bitmap bitmap = new Bitmap((Stream)stream);
                        this.pictureBox1.Image = bitmap;
                        stream.Flush();
                        stream.Close();
                    }

In C# you need to use the Hashtable's indexer: buffer=new Hashtable(); if (table.Rows.Count > 0) { if (this.buffer[this.Flex.Row] == null) { this.buff = (byte[])table.Rows[0][Picture]; this.buffer[this.Flex.Row] = this.buff; } this.lblpic.Visible = false; this.buff = (byte[])this.buffer[this.Flex.Row]; MemoryStream stream = new MemoryStream(this.buff true); stream.Write(this.buff 0 this.buff.Length); Bitmap bitmap = new Bitmap((Stream)stream); this.pictureBox1.Image = bitmap; stream.Flush(); stream.Close(); }
