如何将字符串转换为控制“名称”数据类型？

Question

我有一个名为“customer.cs”的窗体，其中我有一个名为“phonetxt”的文本框，我有一个名为myclass.cs的模型中的类，我有一些代码行 在“customer.cs”中，

dcos package install --package-version=0.9.4.0 kafka

我想要一个将在customer.cs中调用的方法

 private void customerphone_Leave(object sender, EventArgs e)
    {
        if (customerphone.Text != "Enter Phone Number" && customerphone.Text == "")
        {
            this.customerphone.Text = "Enter Phone Number";
            this.customerphone.ForeColor = Color.DarkGray;
            errorcustomerphone.Icon = Properties.Resources.err;
            errorcustomerphone.SetError(customerphone, "Enter Phone Number");
        }

        else
        {
            errorcustomerphone.Icon = Properties.Resources.ok;
            errorcustomerphone.SetError(customerphone, "Enter Phone Number");

        }
    }

有人帮助我，我是c＃的新手。希望你能得到我想要的东西。

这可以是一个很好的起点。

let threshold: Float = 0.05  // Experiment with this to see what feels best.
let lowerBoundary: Float = 1.0 - threshold
let upperBoundary: Float = 1.0 + threshold

if middleSlider.value < lowerBoundary {
    player.volume = 1
    player2.volume = 0
}
else if middleSlider.value <= upperBoundary {
    player.volume = 1
    player2.volume = 1
}
else /* must be middleSlider.value > upperBoundary */ {
    player.volume = 0
    player2.volume = 1
}
