如何在命令的for循环中使用变量？ （c＃）

Question

所以我有一个从a1f到a10f以及从a到j的按钮矩阵，所以a1f在左上方，而j10在右下角。

我想要这样的东西：

for (i = 1; i < 11; i++)
  {
      a{i}f.BackgroundImage = Properties.Resources._1mal2_1_Rebellion;
      b{i}f.BackgroundImage = Properties.Resources._1mal2_2_Rebellion;
      a{i}f.Enabled = false;
      a{i}f.Tag = "playerShip";
      b{i}f.Enabled = false;
      b{i}f.Tag = "playerShip";
  }

所以第一个循环是：

a1f.BackgroundImage = Properties.Resources._1mal2_1_Rebellion;
b1f.BackgroundImage = Properties.Resources._1mal2_2_Rebellion;
a1f.Enabled = false;
a1f.Tag = "playerShip";
b1f.Enabled = false;
b1f.Tag = "playerShip";

第二个是：

a2f.BackgroundImage = Properties.Resources._1mal2_1_Rebellion;
b2f.BackgroundImage = Properties.Resources._1mal2_2_Rebellion;
a2f.Enabled = false;
a2f.Tag = "playerShip";
b2f.Enabled = false;
b2f.Tag = "playerShip";

以此类推。

a {i} f或a [i] f无法正常工作。

如果无法迭代控件，则可以将它们存储在临时数组中。

但是您最好通过生成控件来做。这可能是下一个改进级别。现在，您可以尝试以下方法：

例如：

// create arrays which contains the controls.
var aShips = new [] { a1f, a2f, a3f, a4f, a5f, a6f, a7f, a8f, a9f, a10f };
var bShips = new [] { b1f, b2f, b3f, b4f, b5f, b6f, b7f, b8f, b9f, b10f };

// notice the 0  and the < 10, because arrays are zero-indexed
for (i = 0; i < 10; i++)
{
    // now you can access them via the array. 
    aShips[i].BackgroundImage = Properties.Resources._1mal2_1_Rebellion;
    aShips[i].Enabled = false;
    aShips[i].Tag = "playerShip";

    bShips[i].BackgroundImage = Properties.Resources._1mal2_2_Rebellion;
    bShips[i].Enabled = false;
    bShips[i].Tag = "playerShip";
}
