Okay then

in place of
File.WriteAllBytes(Server.MapPath(imagePath), ConvertHexToBytes(hexString));
Write below code
using (FileStream fs = File.Create(Server.MapPath(imagePath)))
{
    fs.Write(iConvertHexToBytes(hexString), 0, item.File.Length);
}
And run it again

i am capturing it using jquery.

CropedImagePreview.Visible = false;
if (!this.IsPostBack)
{
if (Request.InputStream.Length > 0)
{
using (StreamReader reader = new StreamReader(Request.InputStream))
{
string hexString = Server.UrlEncode(reader.ReadToEnd());
string imagePath = "~/CapturedImage/Image.jpg";
File.WriteAllBytes(Server.MapPath(imagePath), ConvertHexToBytes(hexString));
Session["CapturedImage"] = ResolveUrl(imagePath);
}
}
}
error is file is used by another process... i want capture without close form if file exist then it delete first old file and will be create new file of perticular name.

If you are saving with the same name prior to close the file being saved then you will always face this issue. Always close or release the resources of the file after saving it
