How to manually / programmatically create a DataRow in C#?

To manually or programmatically create a DataRow in C#, you can create a new instance of the DataRow class and add it to a DataTable object.

Here's an example of how to manually create a DataRow in C#:

// Create a new DataTable object DataTable table = new DataTable(); // Add some columns to the DataTable table.Columns.Add("Id", typeof(int)); table.Columns.Add("Name", typeof(string)); table.Columns.Add("Age", typeof(int)); // Create a new DataRow object DataRow row = table.NewRow(); // Set the values of the DataRow's columns row["Id"] = 1; row["Name"] = "John"; row["Age"] = 30; // Add the DataRow to the DataTable table.Rows.Add(row);

In this example, we first create a new DataTable object and add some columns to it using the Columns.Add() method.

We then create a new DataRow object using the NewRow() method of the DataTable object, and set the values of its columns using the indexer ([]) notation.

Finally, we add the DataRow to the DataTable using the Rows.Add() method.

By manually creating DataRow objects in this way, you can programmatically populate a DataTable with data in C#.
