ADO.NET Tutorial - DataTable

This page provides a basic introduction to the DataTable class in .NET. It demonstrates a simple table structure, including header and data cells.

The DataTable is a data structure that holds tabular data in a consistent format. It's a fundamental component of .NET, enabling efficient data management and manipulation.

Data Table Structure

A DataTable consists of columns and rows. Each row represents a record, and each column represents a field. The column definition determines the data type and format of each field.

Column Definition

The DataTable's column definition dictates how data is formatted. For example, a 'Date' column will have a specific format.

Let's say the column definition includes the following:

Date: November 20, 2023

Name: John Doe

Age: 30

City: New York

Data Display

Here's a simple example of how you might display a DataTable:

        

          
            

              Date:
              Name:
              Age:
              City:
            

          
          
            

              November 20, 2023
              John Doe
              30
              New York
            

            

              November 21, 2023
              Jane Smith
              25
              Los Angeles
