how to change timespan variable to a integer type?
提问by Aman Mehrotra
I'm trying to convert timespan variable into an integer variable using 'parse'. I get an error that says:
我正在尝试使用“解析”将时间跨度变量转换为整数变量。我收到一条错误消息：
Format exception was unhandled: Input string was not in correct format
格式异常未处理：输入字符串格式不正确
This is the code is have :
这是代码有：
private void dateTimePicker4_ValueChanged(object sender, EventArgs e)
{
TimeSpan t = dateTimePicker4.Value.ToLocalTime() - dateTimePicker3.Value.ToLocalTime();
int x = int.Parse(t.ToString());
y = x;
}
My target is to display this the change in time for two timepickers, dynamically in a text box, i.e, the difference in minutes between them should be displayed in a textbox automatically.
我的目标是在文本框中动态显示两个时间选择器的时间变化，即它们之间的分钟差应自动显示在文本框中。

它们之间的分钟差应自动显示在文本框中。
Instead of parsing use TimeSpan.TotalMinutesproperty.
而不是解析使用TimeSpan.TotalMinutes属性。
t.TotalMinutes;
The property is of double type, if you just need to integer part then you can do:
该属性是双精度型，如果您只需要整数部分，则可以执行以下操作：
int x = (int) t.totalMinutes;

private void dateTimePicker4_ValueChanged(object sender, EventArgs e)
{
TimeSpan t = dateTimePicker4.Value.ToLocalTime() - dateTimePicker3.Value.ToLocalTime();
int x = int.Parse(t.Minutes.ToString());
y = x;
}
Have you tried changing it to int x = int.Parse(t.Minutes.ToString());?
您是否尝试将其更改为int x = int.Parse(t.Minutes.ToString());？
