How to get row value from DataTable in C#?

In C#, a DataTable is a powerful and flexible data structure used to store and manipulate data in tabular form. If you have a DataTable and want to access a specific row’s value, you can do so by using the Rows collection and indexing the desired row. Here’s how you can get a row value from a DataTable in C#:

**DataRow row = dataTable.Rows[index];**

Once you have obtained the DataRow corresponding to the desired index, you can access the values within that row by using the column name or index. For example, if you want to get the value of the “Name” column in the DataRow, you can use:

**string name = row[“Name”].ToString();**

Similarly, if you know the index of the column, you can use:

**string name = row[columnIndex].ToString();**

By following this approach, you can retrieve and work with specific row values from a DataTable in C# with ease.

Now, let’s address some commonly asked questions related to getting row values from a DataTable in C#.
