ExecuteReader() Method

In This Topic

Sends the CommandText to the Connection and builds a DynamicsDataReader.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Shadows Function ExecuteReader() As DynamicsDataReader

public new DynamicsDataReader ExecuteReader()

Return Value

A DynamicsDataReader object.

Example

The following example creates a DynamicsCommand, then executes it by passing a string that is SQL SELECT statement, and a string to use to connect to the data source.

csharp

public void CreateDynamicsDataReader(string mySelectQuery,string dynamicsConnectionString)
{
  DynamicsConnection dynamicsConnection = new DynamicsConnection(dynamicsConnectionString);
  DynamicsCommand dynamicsCommand = new DynamicsCommand(mySelectQuery, dynamicsConnection);
  dynamicsCommand.Connection.Open();
  DynamicsDataReader dynamicsReader = dynamicsCommand.ExecuteReader();
  try
  {
    while(dynamicsReader.Read())
    {
      Console.WriteLine(dynamicsReader.GetString(0));
    }
  }
  finally
  {
    dynamicsReader.Close();
    dynamicsConnection.Close();
  }
}

Visual Basic

Public Sub CreateDynamicsDataReader(mySelectQuery As String, _
dynamicsConnectionString As String)
  Dim dynamicsConnection As New DynamicsConnection(dynamicsConnectionString)
  Dim dynamicsCommand As New DynamicsCommand(mySelectQuery, dynamicsConnection)
  dynamicsCommand.Connection.Open()
  Dim dynamicsReader As DynamicsDataReader = dynamicsCommand.ExecuteReader()
  Try
    While dynamicsReader.Read()
      Console.WriteLine(dynamicsReader.GetString(0))
    End While
  Finally
    dynamicsReader.Close()
    dynamicsConnection.Close()
  End Try
End Sub
