從SQL Server檢索圖像並將其設置為PictureBox Image屬性

Question

我想使用實體框架從SQL Server（數據庫）檢索圖像並將其設置為PictureBox Image屬性，我已經創建了一個用戶控件並將其繼承到PictureBox（Name：DisplayImage）

    public static void LoadDisplay(Guid? DisplayID, string Name, byte[] image)
    {
        DisplayImage objDisplayImage = new DisplayImage();
        DisplayList.Add(objDisplayImage);
        objDisplayImage.Name = Name;
        MemoryStream ms = new MemoryStream(image);
        Image myImage = Image.FromStream(ms);
        objDisplayImage.Image = myImage;
        objDisplayImage.DisplayID = DisplayID;
        PlayerForm.Instance.Controls.Add(objDisplayImage);
    }

但是圖片沒有加載到PictureBox上

試試這個代碼

try
{
    // get image from object
    byte[] _ImageData = new byte[0];
    _ImageData = (byte[])_SqlRetVal;
    System.IO.MemoryStream _MemoryStream = new System.IO.MemoryStream(_ImageData);
    _Image = System.Drawing.Image.FromStream(_MemoryStream);
}
catch (Exception _Exception)
{
    // Error occurred while trying to create image
    // send error message to console (change below line to customize error handling)
    Console.WriteLine(_Exception.Message);

    return null;
}
