AsyncDataAdapter

Implementation of asynchronous methods on SqlDataAdapter (support for async/await).

The implementation is based on source code provided by Microsoft on GitHub.

Info

• Branch DotNetSource contains original Microsoft .NET sources to simplify resynchronization. Comments contains original sources.
• Only read operations are now supported. Feel free to contribute with the rest.

Sample usage for DataTable

using(varconn=newSqlConnection()){conn.ConnectionString=ConnectionString;awaitconn.OpenAsync();using(varc=conn.CreateCommand()){c.CommandText="GetFast";c.CommandType=CommandType.StoredProcedure;c.Parameters.Add("@Number",SqlDbType.Int).Value=100000;using(vara=newSqlDataAdapter(c)){vardt=newDataTable();varr=awaita.FillAsync(dt);}}}

Sample usage for DataSet

using(varconn=newSqlConnection()){conn.ConnectionString=ConnectionString;awaitconn.OpenAsync();using(varc=conn.CreateCommand()){c.CommandText="GetFast";c.CommandType=CommandType.StoredProcedure;c.Parameters.Add("@Number",SqlDbType.Int).Value=100000;using(vara=newSqlDataAdapter(c)){vards=newDataSet();varr=awaita.FillAsync(ds);}}}
