如何使用组合框选择的索引作为int [英] how to use the combobox selected index as int

问题描述

private void BaudRate_SelectedIndexChanged(object sender, EventArgs e)
       {
           if ((CamPort.IsOpen)) CamPort.Close();
           if (BaudRate.SelectedIndex == -1) return;
           if (string.IsNullOrWhiteSpace(BaudRate.Text)) return;
           //CamPort.BaudRate =(int)BaudRate.Text;
           CamPort.Open();

       }

推荐答案

从您的代码看起来您​​真正想要的是解析所选的值，如所以：

From your code it looks like what you really want is to parse the selected value like so:

CamPort.BaudRate = int.Parse(BaudRate.Text);

如果您想使用所选索引作为标题建议，那么您只需使用它：

If you wanted to use the selected index as your title suggests then you would just use it:

CamPort.BaudRate = BaudRate.SelectedIndex

...但是你的值只有0,1,2等

...But then your value would only be 0,1,2,etc
