我已经搜索过，但找不到正确的答案。请参阅下面的代码并告诉我该怎么做。我的图像框的名称是 picbox 提前致谢

try
{
int w = Convert.ToInt32(RegID.Text);
byte[] image = null;

                    select accom).First();
image = photoRecord.Picture;

}
catch (Exception)

throw;
}

Answer 1

我只添加了两行，它必须完美工作

try
{
int w = Convert.ToInt32(RegID.Text);
byte[] image = null;
{
var photoRecord = (from accom in re.Students
                where accom.RegistrationNo == w
                select accom).First();
image = photoRecord.Picture;
string base64String = Convert.ToBase64String(image, 0, image.Length);
picbox.ImageUrl = "data:image/png;base64," + base64String;
}
}
catch (Exception)
{
throw;
}
