Convert String to Stream correctly for DisplayLayout.Load()
posted

Hey,

 

I've a problem: I saved a gridlayout in a database as string. Then I want to load the layout again from the database. The load-function works for files and streams, so I tried to convert my string into a stream, but everytime I get the exception, that the stream has no correct binary format.

 

I've tried:

       System.IO.TextReader tr = new StringReader(dr["layout"].ToString());
       byte[] a = System.Text.Encoding.Unicode.GetBytes(tr.ReadToEnd());
       System.IO.MemoryStream memStream = new System.IO.MemoryStream(a);
       this.ultraGrid1.DisplayLayout.Load(memStream);

and also:

       System.IO.TextReader tr = new StringReader(dr["layout"].ToString());
       System.IO.MemoryStream memStream = new System.IO.MemoryStream();
       StreamWriter sw = new StreamWriter(memStream);
       sw.Write(tr.ReadToEnd());
       memStream.Seek(0, SeekOrigin.Begin);
       this.ultraGrid1.DisplayLayout.Load(memStream);

 

in both cases I get the exception.

 

I hope there is some help,

greetings

    Stream to string

    System.IO.MemoryStream msLayout = new System.IO.MemoryStream();
    Byte[] byteLayout = msLayout.ToArray();
    string strLayout = Encoding.UTF8.GetString(byteLayout);

    string to stream

    string strLayout;
    Byte[] byteRibbon = Encoding.UTF8.GetBytes(strLayout);
    System.IO.MemoryStream msLayout= new System.IO.MemoryStream(byteLayout);
