Question

我在Winforms应用程序中有关于窗口位置的问题。

我需要在启动时将窗口放在屏幕中央。我尝试了以下但是没有用。表单始终在左上角打开。

我在加载事件中尝试了这些：

this.CenterToScreen();
this.Location = new Point((Screen.PrimaryScreen.WorkingArea.Width - this.Width) / 2,
                          (Screen.PrimaryScreen.WorkingArea.Height - this.Height) / 2);

更新：我已将表格的最大和最小尺寸设为1090,726。

我的设计器文件包含以下代码：

        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.BackColor = System.Drawing.SystemColors.GrayText;
        this.ClientSize = new System.Drawing.Size(1074, 688);
        this.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
        this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
        this.Margin = new System.Windows.Forms.Padding(3, 4, 3, 4);
        this.MaximizeBox = false;
        this.MaximumSize = new System.Drawing.Size(1090, 726);
        this.MinimumSize = new System.Drawing.Size(1090, 726);
        this.Name = "Mail_Remainder";
        this.RightToLeftLayout = true;
        this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;
        this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
        this.Text = "Remainder";
        this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
        this.Load += new System.EventHandler(this.Mail_Remainder_Load);
        this.Resize += new System.EventHandler(this.Mail_Remainder_Resize);
        this.ResumeLayout(false);
        this.PerformLayout();

还有其他方法吗？

请帮忙。

Answer 1

看看以下内容：

 Form1.StartPosition = FormStartPosition.CenterScreen;
 Form1.Show();

编辑：

该行

 this.WindowState = System.Windows.Forms.FormWindowState.Maximized;

是引起偏心的那个。

如果您发表评论：

    private void InitializeComponent()
    {
        this.SuspendLayout();
        // 
        // Form1
        // 
                    this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.BackColor = System.Drawing.SystemColors.GrayText;
        this.ClientSize = new System.Drawing.Size(1074, 688);
        this.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
        this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
        this.Margin = new System.Windows.Forms.Padding(3, 4, 3, 4);
        this.MaximizeBox = false;
        this.MaximumSize = new System.Drawing.Size(1090, 726);
        this.MinimumSize = new System.Drawing.Size(1090, 726);
        this.Name = "Mail_Remainder";
        this.RightToLeftLayout = true;
        this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;
        this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
        this.Text = "Remainder";
//            this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
        this.Load += new System.EventHandler(this.Mail_Remainder_Load);
        this.Resize += new System.EventHandler(this.Mail_Remainder_Resize);
        this.ResumeLayout(false);
        this.PerformLayout();

    }

窗口出现在屏幕中央。

Answer 2

只需将表单的StartPosition属性设置为CenterScreen .....

我有类似的问题;在CenterToScreen（）之后，表单偏离中心。然后我注意到我正在使用InitializeComponent（）进行此操作。我在InitializeComponent之后移动它并且它工作正常。

将winform定位到中心屏幕不起作用
