c# - 用于缩短代码的动态图像名称

Question

我有一个很长的代码，我调用它来检查棋盘上的图 block ，并向具有相同图 block 名称的图片框显示正确的图像。

    private void DisplayBoardDisplayTile(string xtile, string piece)
    {
    if (xtile == "a1")
        {
            if (piece == "0000") { a1.Image = WindowsFormsApplication5.Properties.Resources.S0000; } //empty
            if (piece == "0001") { a1.Image = WindowsFormsApplication5.Properties.Resources.S0001; } //white pawn
            if (piece == "0010") { a1.Image = WindowsFormsApplication5.Properties.Resources.S0010; } //white rook
            if (piece == "0011") { a1.Image = WindowsFormsApplication5.Properties.Resources.S0011; } //white knight
            if (piece == "0100") { a1.Image = WindowsFormsApplication5.Properties.Resources.S0100; } //white bishop
            if (piece == "0101") { a1.Image = WindowsFormsApplication5.Properties.Resources.S0101; } //white queen
            if (piece == "0110") { a1.Image = WindowsFormsApplication5.Properties.Resources.S0110; } //white king
            if (piece == "0111") { a1.Image = WindowsFormsApplication5.Properties.Resources.S0111; } //black pawn
            if (piece == "1000") { a1.Image = WindowsFormsApplication5.Properties.Resources.S1000; } //black rook
            if (piece == "1001") { a1.Image = WindowsFormsApplication5.Properties.Resources.S1001; } //black knight
            if (piece == "1010") { a1.Image = WindowsFormsApplication5.Properties.Resources.S1010; } //black bishop
            if (piece == "1011") { a1.Image = WindowsFormsApplication5.Properties.Resources.S1011; } //black queen
            if (piece == "1100") { a1.Image = WindowsFormsApplication5.Properties.Resources.S1100; } //black king
        }

如果图 block 有阴影，我会使用以“S”开头(如果不是“U”的话)开头的图像名称。它还会检查该片的值与图像名称几乎相同的片。

我想以这样的方式(如果可能的话)缩短代码，使用名为的图像字典

tiles[xtile].Image = ?????."S"+piece;

或类似的东西。

这是 image names 的示例我用过。

可以按名称检索资源:

Image img = (Bitmap)WindowsFormsApplication5.Properties.Resources.ResourceManager.GetObject("S0000");

并且 S 或 U 可以用几个位运算符计算(未测试):

(this.Controls[xtile] as PictureBox).Image = (Bitmap)WindowsFormsApplication5
     .Properties.Resources.ResourceManager.GetObject("SU"[xtile[0] + xtile[1] & 1] + piece);
