saving images from http request

Question

User1024191908 posted

I have a generic http handler that receives an image posted from KENDO UI editor.

inside the handler I try to save the file:

            byte[] buffer = context.Request.BinaryRead(context.Request.TotalBytes);
            FileStream fs = new FileStream(newFileName, FileMode.Create);
            fs.Write(buffer, 0, buffer.Length);
            fs.Close();

but the file that is saved is not an image anymore (it was a jpg) and the file is slightly smaller.

can anyone help please?

thanks in advance.

Hi anooshiravan,

Firstly, please check the following code to make sure you have received a correct byte[].

byte[] buffer = context.Request.BinaryRead(context.Request.TotalBytes);

Then, you can refer the following samples to Save Byte Array as Image In Asp.Net.

public void ProcessRequest(HttpContext context)
{
    string filePath = "MyImageCollection//";

    //handler to catch files from request object.
    if (context.Request.Files.Count <= 0)
    {
        context.Response.Write("No file found");
    }
    else
    {
        for (int i = 0; i < context.Request.Files.Count; ++i)
        {
            HttpPostedFile file = context.Request.Files[i];
            file.SaveAs(context.Server.MapPath(filePath+file.FileName));
            context.Response.Write("File uploaded successfuly");
        }
    }
}
