How Can I Dynamically Access Windows Forms Controls by Name in C#?

In the name of the Windows window control

In C#, the Windows window control is usually obtained by direct reference control name. However, when the control is dynamically generated, this method becomes unrealistic. For this situation, a more dynamic replacement method is needed.

To dynamically access the Windows window control according to the name, you can use the

method. Suppose you have a dynamic Control.ControlCollection.Find called . You want to use the name to access this menu item by programming. myMenu ToolStripMenuItem The following is how to use

Method to achieve this purpose:

Find

A method to accept a string that indicates the name of the control. It returns an array containing the object that matches the name. In this case, you will get a array containing

<code class="language-csharp">string name = "myMenu"; // 注意这里需要用字符串字面量，而不是变量myMenu
Control[] controls = this.Controls.Find(name, true); //第二个参数true表示递归查找子控件
if (controls.Length > 0 && controls[0] is ToolStripMenuItem menuItem)
{
    // 访问并操作控件
    menuItem.Enabled = false; // 例如，禁用菜单项
}
else
{
    // 控件未找到
    Console.WriteLine("Control not found.");
}</code>

. You can then use this array to access and operate control. Find Note: Control myMenu The second parameter of the method is set to ToolStripMenuItem, which means recursive search for subsidiaries. If is not in the direct sub -control of the current window, you need to set it to to find it. If the control is not found, will be 0. For safety reasons, it is recommended to check the control type before accessing the attribute of the control control. Find The method allows you to reference the control through its dynamic name, thereby providing a flexible and efficient mechanism for processing complex and dynamic windows. true
