如何在运行时卸载或清空图片框? [英] How can unload or empty picture box at run time?

问题描述

我在按钮单击事件中使用clear()方法，将数据保存到数据库中后，clear()方法将自动调用.clear()方法包含以下代码.

I use a clear() method in button click event, after save a data in a database the clear() method will call automatically.The clear() method contains the following codes.

txtName.Text = "";
          txtAddress.Text = "";
          txtPhoneNo.Text = "";
          cmbQualification.SelectedIndex = 0;
          cmbStream.SelectedIndex = 0;
          cmbJobType.SelectedIndex = 0;
          dtpDtaeofApply.Value = DateTime.Now;
          cmbLocation.SelectedIndex = 0;
          cmbSubLocationInd.SelectedIndex = 0;
          cmbSubLocationFgn.SelectedIndex = 0;
          txtPassPortNo.Text = "";
          txtAmount.Text = "";

现在我的问题是，在我的按钮单击事件中，我在图片框中添加图像，保存到数据库中后，将调用clear()方法.那时，该图片框应为unload(empty).如何做到这一点?请帮助我.
