How can I easily view the contents of a datatable or dataview in the immediate window

Question

Sometimes I will be at a breakpoint in my code and I want to view the contents of a DataTable variable (or a DataTable in a DataSet).

Answer 1

What I do is have a static class with the following code in my project:

    #region Dataset -> Immediate Window
public static void printTbl(DataSet myDataset)
{
    printTbl(myDataset.Tables[0]);
}
public static void printTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        Debug.Write(mytable.Columns[i].ToString() + " | ");
    }
    Debug.Write(Environment.NewLine + "=======" + Environment.NewLine);
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            Debug.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        Debug.Write(Environment.NewLine);
    }
}
public static void ResponsePrintTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        HttpContext.Current.Response.Write(mytable.Columns[i].ToString() + " | ");
    }
    HttpContext.Current.Response.Write("
" + "=======" + "
");
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            HttpContext.Current.Response.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        HttpContext.Current.Response.Write("
");
    }
}

public static void printTblRow(DataSet myDataset, int RowNum)
{
    printTblRow(myDataset.Tables[0], RowNum);
}
public static void printTblRow(DataTable mytable, int RowNum)
{
    for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
    {
        Debug.Write(mytable.Columns[ccc].ToString() + " : ");
        Debug.Write(mytable.Rows[RowNum][ccc]);
        Debug.Write(Environment.NewLine);
    }
}
#endregion

I then I will call one of the above functions in the immediate window and the results will appear there as well. For example if I want to see the contents of a variable 'myDataset' I will call printTbl(myDataset). After hitting enter, the results will be printed to the immediate window
