Question

I stored my image data in a binary field in sql server
and now I need to convert my byte[] data to string

I used

System.Text.Encoding.ASCII.GetString(data);  
System.Text.Encoding.GetEncoding("shift_jis").GetString(data); 
System.Text.Encoding.GetEncoding("euc-jp").GetString(data);    
System.Text.Encoding.Unicode.GetString(data);   
System.Text.Encoding.UTF8.GetString(data); 

and also Convert.ToBase64String

but they encode my data

how can I convert my data byte[] to string whitout any change?

thanks

I think you got something wrong here.

I need to use this src=”data:image/png;base64,bytes of image”

It says that the data should be base64 encoded so Convert.ToBase64String is what you want in this case.

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA
AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO
