问题描述
如果（Start_date = End_Date）和（Start_date<>NULL）那么
Dim End_date_val As String
End_date_val = END_DATE_DD.Text.ToString（）
Dim Endvalue As Integer
Endvalue = Convert.ToInt32（End_date_val）
$ /
Dim NoOfDays As Integer = DateTime.DaysInMonth（END_DATE_YY.Text，END_DATE_MM.Text）
Endvalue = Endvalue + 1
如果（Endvalue< = NoOfDays）那么
End_Date ='&RSmartUtl.UDConvertDate（Trim （结束价值），修剪（END_DATE_MM.Text），修剪（END_DATE_YY.Text））&'
否则
'********** *****在这里，我想为下一个月的第一天编写End_Date代码。

在其他情况下，我希望获得下个月的第一天可以任何人帮助我出去了？
If (Start_date = End_Date) And (Start_date <> "NULL") Then
Dim End_date_val As String
End_date_val = END_DATE_DD.Text.ToString()
Dim Endvalue As Integer
Endvalue = Convert.ToInt32(End_date_val)
Dim NoOfDays As Integer = DateTime.DaysInMonth(END_DATE_YY.Text, END_DATE_MM.Text)
Endvalue = Endvalue + 1
If (Endvalue <= NoOfDays) Then
End_Date = "'" & RSmartUtl.UDConvertDate(Trim(Endvalue), Trim(END_DATE_MM.Text), Trim(END_DATE_YY.Text)) & "'"
Else

I have above code
If (Endvalue <= NoOfDays) Then
End_Date = "'" & RSmartUtl.UDConvertDate(Trim(Endvalue), Trim(END_DATE_MM.Text), Trim(END_DATE_YY.Text)) & "'"
Else
'*************** Here I want to write code for End_Date as next date that 1st day if Next Month.
End If
In above else condition i want to get 1st day of next month can anybody help me out?

您好，
首先获得系统日期
它在C＃.net
日期时间dt = System.Datetime.Now;
string strNextmonth =1 - +（dt.Month + 1）.ToString（）+ - + dt.Year;
Hi,
First get the System Date
It is in C#.net
Datetime dt= System.Datetime.Now;
string strNextmonth= "1 - " + (dt.Month + 1).ToString() + " - " + dt.Year;
Itis in VB.net
dim dt as datetime
dt = System.Datetime.Now
Dim strNextmonth as string
strNextmonth =1 - +（dt.Month + 1）.ToString（）+ - + dt.Year
