按名称控制,包括儿童

Question

我想通过名字来控制.我写了以下代码:

public Control GetControlByName(string name)
{
    Control currentControl; 

    for(int i = 0,count = Controls.Count; i < count; i++)
    {
        currentControl = Controls[i];

        if (currentControl.HasChildren)
        {
            while (currentControl.HasChildren)
            {
                for(int x = 0,size = currentControl.Controls.Count; x < size; x++)
                {
                    currentControl = currentControl.Controls[x];

                    if (currentControl.Name.Equals(name, StringComparison.OrdinalIgnoreCase))
                    {
                        return currentControl;
                    }
                }
            }
        }
        else
        {
            if (currentControl.Name.Equals(name, StringComparison.OrdinalIgnoreCase))
            {
                return currentControl;
            }
        }
    }

    return null;
}

它只返回null.有人可以指出我的错误吗？欢迎任何帮助或改进此代码的方法.

只需使用Controls集合查找方法:

            var aoControls = this.Controls.Find("MyControlName", true);
            if ((aoControls != null) && (aoControls.Length != 0))
            {
                Control foundControl = aoControls[0];
            }
