循环遍历特定 DataTable 的行

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.

Answer 1

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".

Answer 2

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

Answer 3

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
    Next

Answer 4

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
