How to Access Dynamically Generated Windows Forms Controls by Name?

Dynamic access to Windows Forms controls by name

When using dynamically generated controls in Windows Forms, it can be difficult to access them programmatically using their dynamically assigned names. This becomes necessary when referencing menu items created from XML files.

Question:

How do we access the ToolStripMenuItem by name even though it is dynamically generated?

Consider the following situation:

<code>// 常规方法（对于动态生成的控件不可行）
ToolStripMenuItem myMenu = this.myMenu;

// 期望方法（可以通过名称引用控件）
string name = myMenu;
this.name...</code>

Solution:

The key to dynamically accessing controls is to use the Control.ControlCollection.Find method. This method allows us to search for a control in the control collection based on its name.

To access a ToolStripMenuItem by name, you can use the following code:

<code>this.Controls.Find(name);</code>

This will return an array of controls matching the specified name. You can then access the first control in the array to reference the menu item.

For example:

<code>ToolStripMenuItem myMenu = 
    (ToolStripMenuItem)this.Controls.Find(name)[0];</code>

Using this method, you can dynamically reference menu items by name, even if they are created at runtime.
