我无法在FormLoad中调整表单的大小 [英] I could not Resize the form in FormLoad

问题描述

我想设置 一半 屏幕大小的形式.这就是我写的内容

I want to set the size of the form half the size of the screen.this is what i have wrote

<pre lang="cs">using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace ScreenSize
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void frmMain_Load(object sender, EventArgs e)
        {
          int ScreenWidth, ScreenHeight;
          ScreenWidth =System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width;
          ScreenHeight = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height;

          MessageBox.Show("ScreenWidth =" + ScreenWidth.ToString(), " ScreenHeight =" + ScreenHeight.ToString());

//none of the following works
        //Form1.ActiveForm.Size = new System.Drawing.Size(ScreenWidth /2, ScreenHeight /2);
        //Form1.Size = new System.Drawing.Size(ScreenWidth /2, ScreenHeight /2);
        //Form1.ActiveForm.Width=ScreenWidth/2;
        //Form1.ActiveForm.Height=ScreenHeight/2;

        }
    }
}

推荐答案

是的，但是您没有这样做:

Yeah, but you didn''t do this:

this.Size = new Size(ScreenWidth/2, ScreenHeight/2);

您不需要Form1.ActiveForm-您想影响当前实例.
试试:

You don''t need Form1.ActiveForm - you want to affect the current instance.
Try:

private void frmTesting_Load(object sender, EventArgs e)
    {
    int ScreenWidth, ScreenHeight;
    ScreenWidth = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width;
    ScreenHeight = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height;
    Width = ScreenWidth / 2;
    Height = ScreenHeight / 2;
    }

这应该可以解决您的问题

this should fix your problem

int ScreenWidth = Screen.GetWorkingArea(this).Width / 2;
            int ScreenHeight = Screen.GetWorkingArea(this).Height / 2;
this.Size = new Size(ScreenWidth, ScreenHeight);

如果您希望表单居中，请尝试使用此

if you want the form to be centered try to use this

this.StartPosition = FormStartPosition.Manual;            
            int ScreenWidth = Screen.GetWorkingArea(this).Width / 4;
            int ScreenHeight = Screen.GetWorkingArea(this).Height / 4;
            this.Location = new Point(ScreenWidth, ScreenHeight);
            this.Size = new Size(ScreenWidth*2, ScreenHeight*2);
