範例

下列範例會使用 GetDatabaseInfo 擷取 Northwind.sdf 的資料庫屬性。SqlCeConnection 會傳遞連接字串，然後開啟與資料庫的連接。連接開啟後，GetDatabaseInfo 的內容就會儲存在 KeyValuePair 中並顯示在主控台上。

Dim connStr As String = Nothing
Dim databasePath As String = Nothing
Dim sqlconn As SqlCeConnection = Nothing

Try
    'Defining database parameters
    databasePath = "C:\Program Files\Microsoft SQL Server Compact Edition\v3.5\Samples\Northwind.sdf"
    'If the database already exists, the existing encryption mode will supercede the supplied mode
    connStr = "Data Source=" & databasePath & ";Encryption Mode = 'ppc2003 compatibility';Password='password'"

    'Connecting to the database and opening the connection
    sqlconn = New SqlCeConnection(connStr)
    sqlconn.Open()

    'Retrieving the database information
    Dim dbinfo As List(Of KeyValuePair(Of String, String)) = sqlconn.GetDatabaseInfo

    Console.WriteLine("GetDatabaseInfo() results:")
    Dim kvp As KeyValuePair(Of String, String)

    For Each kvp In dbinfo
        Console.WriteLine(kvp)
    Next

Catch ex As Exception
    Console.WriteLine(ex.Message)

Finally
    'Dispose the connection's resources
    sqlconn.Dispose()

    Console.WriteLine(vbNewLine & vbNewLine & vbNewLine & "Press any key to continue...")
    Console.Read()
End Try

string connStr = null;
string databasePath = null;
SqlCeConnection sqlconn = null;

try
{
    //Defining database parameters
    databasePath = @"C:\Program Files\Microsoft SQL Server Compact Edition\v3.5\Samples\Northwind.sdf";
    //If the database already exists, the existing encryption mode will supercede the supplied mode
    connStr = "Data Source=" + databasePath + ";Encryption Mode = 'ppc2003 compatibility';Password='sa'";

    //Connecting to the database and opening the connection
    sqlconn = new SqlCeConnection(connStr);
    sqlconn.Open();

    //Retrieving the database information 
    List<KeyValuePair<string, string>> dbinfo = sqlconn.GetDatabaseInfo();

    Console.WriteLine("GetDatabaseInfo() results:");

    foreach (KeyValuePair<string, string> kvp in dbinfo)
    {
        Console.WriteLine(kvp);
    }

}
catch (Exception ex)
{
    Console.WriteLine(ex.Message);
}
finally
{
    //Dispose the connection's resources
    sqlconn.Dispose();

    Console.WriteLine("\n\n\nPress any key to continue...");
    Console.Read();
}
