我试图通过两种方法绑定数据集“data_set”中数据表“申请人详细信息”中“申请人图像”列中的图像。但是当我运行表单应用程序时，我看不到图片框“imgusr”中显示的图像。我的绑定源名称是“bindSource”。

假设 data_set 正确检索了所有内容，图像未加载到图片框“imgusr”中可能有什么问题？？

此外，sizeMode 的图片框属性为“缩放”。

    private void Update_Load(object sender, EventArgs e){
        data_set = blobj.srcforVU();
        bindSource.DataSource = data_set;
        bindSource.DataMember = "Applicant's Details";

        //method 1
        //Binding binding = new Binding("Image", bindSource, "Applicant's Image", true, DataSourceUpdateMode.OnPropertyChanged);
        //binding.Format += new ConvertEventHandler(binding_Format);
        //imgusr.DataBindings.Add(binding);
        //method 2
        imgusr.DataBindings.Add(new Binding("Image", bindSource, "Applicant's Image", true));

        tbfname.DataBindings.Add(new Binding("Text", bindSource, "First Name", true));
        tblname.DataBindings.Add(new Binding("Text", bindSource, "Last Name", true));
        tbgender.DataBindings.Add(new Binding("Text", bindSource, "Gender", true));
        tbbdate.DataBindings.Add(new Binding("Text", bindSource, "Birth Date", true));
        tbmob.DataBindings.Add(new Binding("Text", bindSource, "Mobile …
