int days =（（TimeSpan）（endDate-startDate））。天;

int days = ((TimeSpan)(endDate-startDate)).Days;

嗨Andy，


VB中的DateDiff有点像历史。


这可以在VB 2008中

\\\

Dim EndDate = DateTime.Now

Dim StartDate = Now.AddDays（-3）

Dim days = EndDate - StartDate

MessageBox.Show（days.Days.ToString）

///


这可以在C＃2008中

\\\\

var EndDate = DateTime.Now;

var StartDate = DateTime.Now.AddDays（-3 ）;

var days = EndDate - StartDate;

MessageBox.Show（days.Days.ToString（））;

///


我真的没有看到太多差异。


仅在这种情况下VB代码表明问题有点< br $> b $ b奇怪。

Hi Andy,

DateDiff in VB is a little bit from pre history.

This it can be in VB 2008
\\\
Dim EndDate = DateTime.Now
Dim StartDate = Now.AddDays(-3)
Dim days = EndDate - StartDate
MessageBox.Show(days.Days.ToString)
///

This it can be in C# 2008
\\\\
var EndDate = DateTime.Now;
var StartDate = DateTime.Now.AddDays(-3);
var days = EndDate - StartDate;
MessageBox.Show(days.Days.ToString());
///

I real don''t see much differences.

The VB code only in this case to show that the question is a little bit
strange.

你好，Andy，


VB中的DateDiff有点偏离历史。

这可以在VB 2008中

\\\

Dim EndDate = DateTime.Now

Dim StartDate = Now.AddDays（-3）

Dim days = EndDate - StartDate

MessageBox.Show（days.Days.ToString）

///

\\\\

var EndDate = DateTime.Now;

var StartDate = DateTime.Now.AddDays（-3）;

var days = EndDate - StartDate;

MessageBox .Show（days.Days.ToString（））;

///


我真的没看多少差异。


VB代码只在这种情况下显示问题有点

奇怪。
