          imc.ShowDialog(this);

       {


           NewClient pictureSource=new NewClient();
           pictureSource.PBProfilePic.Image = this.pictureBox2.Image;

           this.Hide();
       }

推荐答案

因为每次单击Button1都会创建表单的新实例，所以不应该隐藏它 - 相反，转到ProfilepictureCapture表单，并将btnok按钮的DialogResult属性设置为DialogResult.OK

现在，当用户单击确定按钮时，表单将关闭，控件将返回到原始表格。

在ProfilepictureCapture表单中添加一个属性：

Because you create a new instance of the form each time you click Button1, you shouldn't Hide it - instead, go to the ProfilepictureCapture form, and set the DialogResult property of the btnok button to DialogResult.OK
Now, when the user clicks the OK button, the form will close and control will return to the original form.
Add a property to the ProfilepictureCapture form:

public Image ProfilePic
   {
   get { return pictureBox2.Image; }
   }

然后在您的呼叫表单中使用该属性：

And then use that property in your calling form:

private void Button1_Click(object sender, EventArgs e)
      {
          ProfilepictureCapture imc = new ProfilepictureCapture();
          if (imc.ShowDialog(this) == DiralogResult.OK)
          {
              Image myPicture = imc.ProfilePic;
              ...
          }
      }
