Often with date calculations, something starts working at a certain time, and after n hours of work (working time only), what time is expected to be completed DT1?Suppose the working time is 9:00-18:00, 9 hours a day ... Well, I'll forget about 1 hours at noon.Now there is dt1 start time, N hours, DT2, end time.1. If the direct use of DT1 + N, the time is less good, slightly a large, it will be the end of the night or the nth day of the night ... Obviously unreasonable.2. Consider the time of th

The merge method combines two data tables with similar structures into one data table:
Instance
Code :
// Create Table1 Datatable dt1 = New Datatable (); dt1.columns. Add ( " ID " ); Dt1.columns. Add ( " Name " ); Dt1.columns. Add ( " PWD " ); For ( Int I = 0 ; I 5 ; I ++ ) {Dt1.rows. Add ( New Object [] {I. tostring (), " Name " + I. tostring (), " ** " });} // Create Table2 Datatable dt2 = New Datatable (); dt2.columns. A
First, create two xtrareport. One is the master and the other is the slave

A. DateTime
In C #, the system provides a lot of functions about time processing, and we can get the system time through System.DateTime.Now. Of course, you can also use a DateTime class to create a time object. Here are a few examples of how to get the system time.
DateTime DT1 = new DateTime (2004, 10, 19);Console.WriteLine ("DT1: {0}", DT1);DateTime DT2 = new DateTime (2004, 10, 19, 22, 47, 35);Console.WriteLine ("DT2: {0}", DT2);DateTime DT
write as follows:
Datatable dt1 = new datatable (); // instantiate class datatable dt2; // defines an object, but does not instantiate datatable dt3; // defines an object, but does not instantiate dt2 = dt1; // pass the first address of the Instance stored in dt1 to dt2dt3 = dt2; // send the first address of the Instance stored in dt2 to dt3
This method is completely feasible! If it is instanti
