EntityConnectionStringBuilder 생성자

public:
 EntityConnectionStringBuilder();

public EntityConnectionStringBuilder();

Public Sub New ()

예제

다음 예제에서는 in과 함께 사용 EntityConnectionStringBuilder 하는 방법을 보여 줍니다 SqlConnectionStringBuilder. 코드는 SqlConnectionStringBuilder 속성을 설정하여 기본 공급자 연결 문자열 일부를 제공하는 SqlConnection 연결 문자열 만듭니다. 공급자 이름은 SqlConnectionStringBuilder 사용하여 설정할 수 없습니다. SqlConnection 연결 문자열 구문이 잘못되었기 때문입니다. 이 코드는 EntityConnectionStringBuilder 속성을 설정하여 EntityConnection 연결 문자열 만듭니다.

설명

제공된 connectionString 키워드/값 쌍이 유효한지 확인하지 않습니다. 유효한 키워드/값 구문은 .를 참조하세요 ConnectionString.

매개 변수에 고정 공급자 이름을 지정 connectionString 해야 합니다. 지원되는 공급자는 다음과 같습니다.

• System.Data.Odbc
• System.Data.OleDb
• System.Data.OracleClient
• System.Data.SqlClient
• Microsoft.SqlServerCe.Client
