DateTime – Aktueller Datum minus 20 Tage

MetinC — Tue, 26 Jun 2012 13:05:48 +0000

In Visual Basic gibt es die Funktionen DateAdd und DateDiff, mit denen man den DateTime manipulieren kann. Diese sind in CSharp .NET nicht implementiert. Ich hatte mir überlegt, wie ein Kollege aus Indien die Funktionen selbst zu implementieren, wie hier: DateDiff and DateAdd in C#

Aber es geht einfacher mit einem zweizeiligen C# Code:

            DateTime dt = DateTime.Now;
            dt = dt.AddDays(-20);

ListViewItem item3 = new ListViewItem("Item 3", 1);
item3.SubItems.Add("Item3 Subitem 1");

//Add the items to the ListView.
listView1.Items.AddRange(new ListViewItem[] { item1, item2, item3 });

// add a row with an item

column1.TextAlign = HorizontalAlignment.Right;            
listView1.Columns.Add(column1);

listView1.Columns.Add("Column 2", 120, HorizontalAlignment.Center);

// Width of -1 indicates to adjust the width of the longest item in the column.
listView1.Columns.Add("Column 3", -1, HorizontalAlignment.Left);

// Width of -2 indicates to autosize to the width of the column heading.
