如何从C#中的'字符串名称获取对控件的引用

Control control = FindControl("控件名称");

Control control = this.Controls["控件名称"];

Control FindControlRecursive(Control root, string controlID)
{
    if (root.ID == controlID)
        return root;

    foreach (Control controlToSearch in root.Controls)
    {
        Control controlFound = FindControlRecursive(controlToSearch, controlID);
        if (controlFound != null)
            return controlFound;
    }

    return null;
}

Control control = FindControlRecursive(this, "控件名称");
