From DataTable in C# .NET to JSON

Question

I am pretty new at C# and .NET, but I\'ve made this code to call a stored procedure, and I then want to take the returned DataTable and convert it to JSON.

Answer 1

I use JavaScriptSerializer + LINQ

return new JavaScriptSerializer().Serialize(
  dataTable.Rows.Cast()
  .Select(row => row.Table.Columns.Cast()
    .ToDictionary(col => col.ColumnName, col => row[col.ColumnName]))
  .ToList()
);
