如何在C＃中的文本框末尾添加单位

Question

I find this code from here to add a unit like minutes or kg at the end of a textbox after the number was entered. in C#

private void CowAgetxtBox_Leave(object sender, EventArgs e)
    {
        {
            CowAgetxtBox.Text = CowAgetxtBox.Text + " Month";
        }
    }

    private void CowAgetxtBox_Enter(object sender, EventArgs e)
    {
        {
            CowAgetxtBox.Text = CowAgetxtBox.Text.Replace(" Month", "");
        }
    }

but I don't know how get that number, I use this Code but it doesn't work

int Age = int.Parse(CowAgetxtBox.Text);

Answer 1

实际上，将单元放置在文本框中不是一个好主意，这会在数据验证，本地化，转换等方面引起很多问题，最好将其放置在文本框中:)

Answer 2

You just need to do a process similar you when the user focused on the text box.

int Age = int.Parse(CowAgetxtBox.Text.Replace(" Month", ""));

This will get the job done.

Answer 3

It seems that

         CowAgetxtBox.Text

this statement contains value other then number thats why this statment

        int Age = int.Parse(CowAgetxtBox.Text);

is not working remove " Month" from the first function

Answer 4

You can add a property like the following:

int Age {
get { return Convert.ToInt32(CowAgetxtBox.Text.Replace(" Month", ""));     }
}

Answer 5

如果单位标签发生变化，这可能会在更多情况下为您服务：

int Age = int.Parse(CowAgetxtBox.Text.Split(' ')[0]);
