如何在C＃中设置FlowLayoutPanel的位置？

在Windows窗体中，FlowLayoutPanel控件用于在水平或垂直流方向上排列其子控件。换句话说，FlowLayoutPanel是一个容器，用于在其中水平或垂直地组织不同或相同类型的控件。在FlowLayoutPanel控件中，您可以使用Location Property在表单中设置控件的位置。此属性为您提供FlowLayoutPanel的x和y坐标。您可以通过两种不同的方式设置此属性：

1.设计时：这是设置FlowLayoutPanel位置的最简单方法，如以下步骤所示：

• 第1步：创建一个Windows窗体，如下图所示：
  Visual Studio->文件->新建->项目-> WindowsFormApp
  
• 步骤2：接下来，将FlowLayoutPanel控件从工具箱拖放到窗体，如下图所示：

  

• 步骤3：拖放之后，您将转到FlowLayoutPanel的属性并设置FlowLayoutPanel的位置，如下图所示：

  

  输出：

  

2.运行时：比上述方法有些棘手。在此方法中，您可以借助给定的语法以编程方式设置FlowLayoutPanel控件的位置：

public System.Drawing.Point Location { get; set; }

这里，Point表示FlowLayoutPanel的坐标。以下步骤显示了如何动态设置FlowLayoutPanel的位置：

• 步骤1：使用FlowLayoutPanel类提供的FlowLayoutPanel()构造函数创建FlowLayoutPanel。

  // Creating a FlowLayoutPanel
  FlowLayoutPanel f = new FlowLayoutPanel();
  

• 步骤2：创建FlowLayoutPanel后，设置FlowLayoutPanel类提供的FlowLayoutPanel的Location属性。

  // Setting the location
  f.Location = new Point(380, 124);
  

• 步骤3：最后，将此FlowLayoutPanel控件添加到表单中，并使用以下语句在FlowLayoutPanel中添加子控件：

  // Adding a FlowLayoutPanel 
  // control to the form
  this.Controls.Add(f);
  
  and 
  
  // Adding child controls 
  // to the FlowLayoutPanel
  f.Controls.Add(r1);
  

例子：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
  
namespace WindowsFormsApp50 {
  
public partial class Form1 : Form {
  
    public Form1()
    {
        InitializeComponent();
    }
  
    private void Form1_Load(object sender, EventArgs e)
    {
        // Creating and setting the
        // properties of FlowLayoutPanel
        FlowLayoutPanel f = new FlowLayoutPanel();
        f.Location = new Point(380, 124);
        f.Size = new Size(216, 57);
        f.Name = "Mycontainer";
        f.Font = new Font("Calibri", 12);
        f.FlowDirection = FlowDirection.RightToLeft;
        f.BorderStyle = BorderStyle.Fixed3D;
        f.ForeColor = Color.BlueViolet;
        f.Visible = true;
  
        // Adding this control
        // to the form
        this.Controls.Add(f);
  
        // Creating and setting the 
        // properties of radio buttons
        RadioButton r1 = new RadioButton();
        r1.Location = new Point(3, 3);
        r1.Size = new Size(95, 20);
        r1.Text = "R1";
  
        // Adding this control 
        // to the FlowLayoutPanel
        f.Controls.Add(r1);
  
        RadioButton r2 = new RadioButton();
        r2.Location = new Point(94, 3);
        r2.Size = new Size(95, 20);
        r2.Text = "R2";
  
        // Adding this control to
        // the FlowLayoutPanel
        f.Controls.Add(r2);
  
        RadioButton r3 = new RadioButton();
        r3.Location = new Point(3, 26);
        r3.Size = new Size(95, 20);
        r3.Text = "R3";
  
        // Adding this control to 
        // the FlowLayoutPanel
        f.Controls.Add(r3);
    }
}
}

输出：
