将两次之间的差异转换为毫秒? [英] Convert Difference between 2 times into Milliseconds?

问题描述

我有两个屏蔽的 TextBox 控件，想知道如何在每个控件中获取时间，然后将差异转换为毫秒.比如，在 tb1 中我写12:01"，在 tb2 中我写12:02"，然后单击一个按钮.单击按钮后，它将启动一个计时器，并在 12:02 显示一个消息框.除了时间转换部分，我知道怎么做.

I have two masked TextBox controls and was wondering how I'd go about getting the time in each one and then converting the difference into milliseconds. Like, say in tb1 I write "12:01" and in tb2 I write "12:02", and then click a button. Once the button's clicked it starts a timer and at 12:02 a messagebox will be displayed. I know how to do all of it except for the time conversion part.

如何实现?

推荐答案

DateTime dt1 = DateTime.Parse(maskedTextBox1.Text);
DateTime dt2 = DateTime.Parse(maskedTextBox2.Text);
TimeSpan span = dt2 - dt1;
int ms = (int)span.TotalMilliseconds;
