我点击按钮时尝试更改标签,但由于某种原因它无法正常工作。它一直在工作,直到我做了一点改变,我不知道该怎么做了。有人可以帮忙吗?这是代码:

private void btnColorChange_Click(object sender, EventArgs e)
    {
        if (lblTvalue.Text = "1")
        {
            lblTest.Text = "$0.00";
        }
        if (lblTvalue.Text = "2")
        {
            lblTest.Text = "$2.00";
        }
    }

确保在IF(x.x == x)中放置2 " equals" ,如:

private void btnColorChange_Click(object sender, EventArgs e)
{
    if (lblTvalue.Text == "1")
    {
        lblTest.Text = "$0.00";
    }
    if (lblTvalue.Text == "2")
    {
        lblTest.Text = "$2.00";
    }
}
