推荐答案

您可以像@Christian Sauer 所说的那样迭代所有控件，但如果任何控件是控件的容器，您可能会遇到问题.你需要做一个递归搜索来解决这个问题.但是，ControlCollection 实际上有一个 Find() 方法，您可以使用.它返回与名称匹配的控件数组，并可选择执行递归搜索.

You could iterate over all of the controls as @Christian Sauer said but you might run into problems if any controls are containers of controls. You'd need to do a recursive search to solve that. However, the ControlCollection actually has a Find() method that you can use. It returns an array of controls that match the name and optionally performs a recursive search.

    ''//Our final control
    Dim someVariable As Control = Nothing
    ''//Search recursively for our control
    Dim SearchedControls = Me.Controls.Find(key:="Label1", searchAllChildren:=True)
    ''//If we found one and only one control
    If SearchedControls.Count = 1 Then
        ''//Set it to our variable
        someVariable = SearchedControls(0)
    Else
        ''//Whatever your logic dictates here
    End If
