带有文本框名称的foreach循环

Question

我如何从这个做一个foreach循环，我想只改变以txt2结尾的文本框的大小

        br1txt2.Size = new Size(27, 20);
        br2txt2.Size = new Size(27, 20);
        br3txt2.Size = new Size(27, 20);
        br4txt2.Size = new Size(27, 20);
        br5txt2.Size = new Size(27, 20);

Answer 1

Size newSize = new Size(27, 20);
foreach (Control c in this.Controls)
{
   if (c is TextBox && c.Name.EndsWith("txt2"))
   {
      c.Size = newSize;
   }
}

Answer 2

多年来没有做过任何胜利，但我认为这可能会成功

IEnumerable<TextBox> textBoxes = GetTextBoxes() //Get your textboxes from wherever
Size newSize = new Size(27, 20);
foreach (Control c in textBoxes.Where(c=>c.Name.EndsWith("txt2")))
{
   c.Size = newSize;
}

Answer 3

TextBox[] tBoxesForSizeChange = new TextBox[2] {br1txt2, br2txt2 };
Size newSize = new Size(27, 20);

foreach(TextBox tBox in tBoxesForSizeChange)
{
   tBox.Size = newSize;
}

代码可能无法编译 但是，我希望它能让你进一步构建。
