SqlCeConnection Class

Represents an open connection to a data source.

Namespace: System.Data.SqlServerCe
Assembly: System.Data.SqlServerCe (in system.data.sqlserverce.dll)

public sealed class SqlCeConnection : DbConnection
public final class SqlCeConnection extends DbConnection
public final class SqlCeConnection extends DbConnection

A SqlCeConnection object represents a unique connection to a data source. When you create an instance of SqlCeConnection, all properties are set to their initial values. For a list of these values, see the SqlCeConnection constructor.

If the SqlCeConnection goes out of scope, it is not closed. You must explicitly close the connection by calling Close or Dispose.

SQL Server Mobile supports multiple simultaneous connections as well as multiple commands sharing the same connection. This means that it is possible to have multiple instances of SqlCeDataReader open on the same connection. This behavior differs from that of System.Data.SqlClient.

If a fatal SqlCeException is generated by the method executing a SqlCeCommand, the SqlCeConnection may be closed. You can reopen the connection and continue.

The following example creates a SqlCeCommand and a SqlCeConnection. The SqlCeConnection is opened and set as the Connection for the SqlCeCommand. The example then calls ExecuteNonQuery and closes the connection.

SqlCeConnection conn = null;

try
{
    conn = new SqlCeConnection("Data Source = MyDatabase.sdf; Password ='<pwd>'");
    conn.Open();

    SqlCeCommand cmd = conn.CreateCommand();
    cmd.CommandText = "INSERT INTO Customers ([Customer ID], [Company Name]) Values('NWIND', 'Northwind Traders')";

    cmd.ExecuteNonQuery();

finally
{
    conn.Close();
