Populate from Data Adapter:

We can fill the dataset by calling the Fill() method of the Data Adapter class. Below is the full code that will fill the database.

string conn = "You connection string will goes here";


SqlConnection conn = new SqlConnection(conn);

SqlDataAdapter da = new SqlDataAdapter(strSQL, conn);

DataSet ds = new DataSet();

da.Fill(ds, "Employees");

Also you can call the fill method like below:


But when you want to retrieve then you have to retrieve using the index like ds.Tables[0].

But in the above method you can retrieve like ds.Tables["Employees"].

Populate from XML:

To load XML into a DataSet class, we have to call the ReadXML() method like below:

DataSet ds = new DataSet();
