Loop through the rows of a particular DataTable
Question
IDE : VS 2008, Platform : .NET 3.5,
Hi,
Here is my DataTable columns :
ID Note Detail
I want to write sth like this :
//below code block is not the right syntax
For each q in dtDataTable.Column("Detail")
strDetail = Row of Column Detail
Next
Can anyone give me a suggestion and show me a code sample please ? Thanks.
Solution
For Each row As DataRow In dtDataTable.Rows
strDetail = row.Item("Detail")
Next row
There's also a shorthand:
For Each row As DataRow In dtDataTable.Rows
strDetail = row("Detail")
Next row
Note that Microsoft's style guidelines for .Net now specifically recommend against using hungarian type prefixes for variables. Instead of "strDetail", for example, you should just use "Detail".
OTHER TIPS
Dim row As DataRow
For Each row In dtDataTable.Rows
Dim strDetail As String
strDetail = row("Detail")
Console.WriteLine("Processing Detail {0}", strDetail)
Next row
You want to loop on the .Rows, and access the column for the row like q("column")
Just:
For Each q In dtDataTable.Rows
strDetail = q("Detail")
Next
Also make sure to check msdn doc for any class you are using + use intellisense
Here's the best way I found:
For Each row As DataRow In your_table.Rows
For Each cell As String In row.ItemArray
'do what you want!
Next
