C# 按钮文本和调整大小

Question

我有一个简单的按钮，单击该按钮时应将文本从“帮助”更改为“隐藏”以及窗口窗体大小。我遇到的问题是找不到 if 语句。它看不到 button3.text 帮助或隐藏。有什么提示或建议吗？

private void button2_Click(object sender, EventArgs e)
{
        string helpstring = "Help";
        string hidestring = "Hide";
        if (button3.Text == helpstring)
        {
            button3.Text = hidestring;
            Size = new System.Drawing.Size(1106, 563);
        }
        if (button3.Text == "Hide")
        {
            Size = new System.Drawing.Size(586, 563);
            button3.Text = helpstring;
        }
    }

Answer 1

您忘记了“else”。这应该有效:

private void button2_Click(object sender, EventArgs e)
{
    string helpstring = "Help";
    string hidestring = "Hide";
    if (button3.Text == helpstring)
    {
        button3.Text = hidestring;
        Size = new System.Drawing.Size(1106, 563);
    }
    else if (button3.Text == "Hide") //this is where you should put an else
    {
        Size = new System.Drawing.Size(586, 563);
        button3.Text = helpstring;
    }
}
