示例

以下示例创建 OdbcConnection 并显示后端数据源名称。

public void CreateOdbcConnection()
{
    string connectionString = "...";

    using (OdbcConnection connection = new(connectionString))
    {
        connection.Open();
        Console.WriteLine($"ServerVersion: {connection.ServerVersion}"
            + $"\nDatabase: {connection.Database}");

        // The connection is automatically closed at
        // the end of the Using block.
    }
}

Public Sub CreateOdbcConnection(connectionString As String)
       Using connection As New OdbcConnection(connectionString)
           With connection
               .Open()
               Console.WriteLine("ServerVersion: " & .ServerVersion _
                  & vbCrLf + "Database: " & .Database)
           End With
       End Using 
End Sub

注解

检索 DataSource 属性等效于调用将 参数设置为 SQL_SERVER_NAME 的 ODBC 函数SQLGetInfoInfoType。
