c# - 在父级的中心显示对话框

Question

在其父窗体的中心显示一个 DialogBox 真是一团糟。这是显示对话框的方法。

我将其父级定位到中心但无法使 DialogBox 居中

private void OpenForm(Object point, Object height, Object width)
{
    FormLoading frm = new FormLoading();
    Point temp = (Point)point;
    Point location = new Point(temp.X + (int)((int)width) / 2, 
                               temp.Y + (int)((int)height) / 2);
    frm.Location = location;
    frm.ShowDialog();
}

private void btnView_Click(object sender, EventArgs e)
{
    try
    {                    
        ThreadStart starter= delegate { OpenForm(currentScreenLocation, 
                                                 this.Height, this.Width); };
        Thread t = new Thread(starter);
        t.Start();
        ////// Some functionality here...
        t.Abort();
    }
    catch (Exception)
    {
    }
}

Answer 1

您可能需要检查 Form.StartPosition 属性。

http://msdn.microsoft.com/en-us/library/system.windows.forms.form.startposition.aspx

类似的东西:

private void OpenForm(Form parent)
{
    FormLoading frm = new FormLoading();
    frm.Parent = parent;
    frm.StartPosition = FormStartPosition.CenterParent;
    frm.ShowDialog();
}

这当然需要设置表单的父级。
