C# 动态操作 控件位置绑定 [ Anchor ] 属性

注:

1.此类属于非常用类,只因本人需要编写的...顺便刷贴一下

2.对于初学,其中的枚举使用可以为你加深一点印象

 

以下为操作类代码:

                #endregion

以下为操作类关联函数代码:

/// <summary>
/// 输出: 控件 Anchor 上下左右 01 表示标识,如:上左=1010 , None="-1",默认为:空;
/// </summary>
/// <param name="achStl"></param>
/// <param name="sigs"></param>
/// <param name="sigCnt">有多少个 sig </param>
public static void Sigs(AnchorStyles achStl, out string sigs, out int sigCnt)
{
    string achs = achStl + "";
    achs = achs.Replace(" ", "");

    sigCnt = 0;
    sigs = "-1";
    if (achs == N)
        return;

    string[] achS = achs.Split(c.d);
    List<string> achL = new List<string>(achS);

    int cnt = namL.Count, idx;
    string ach;
    sigs = "";
    for (int i = 0; i < cnt; i++)
    {
        ach = namL[i];
        idx = achL.IndexOf(ach);
        if (idx < 0)
            sigs += '0';
        else
        {
            sigs += '1';
            sigCnt++;
        }
    }
    return;
}

使用方法:

1.初始化:Achctrer ctrer=new Achctrer(四点个[方向顺序:上下左右]控件);

2.参数属性说明:

a.IGetAchChtr:此属性用于获取你要操作 Anchor 属性的控件

b.IOutAchSigs:此参数作为输出参数,其输出值为 Anchor 标识[此标识为本人自定义],例:-1=None,""=默认,1010=上左
