将字符串从Startup.cs方法传递到数据库

Question

我有一个问题，我的Asp.Net Core RC1项目中的Startup.cs类中有我的Websocket方法。

    private async Task Echo(WebSocket webSocket)
    {
        var buffer = new byte[1024 * 4];
        var result = await webSocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);
        string text = "";
        while (!result.CloseStatus.HasValue)
        {
            await webSocket.SendAsync(new ArraySegment<byte>(buffer, 0, result.Count), result.MessageType, result.EndOfMessage, CancellationToken.None);
            result = await webSocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);

            for (int i = 0; i < result.Count; i++)
            {
                text += (char) buffer[i];
            }
            /*

             TODO: ADD {text} to Database

             */
            text = text ?? "";
        }
        await webSocket.CloseAsync(result.CloseStatus.Value, result.CloseStatusDescription, CancellationToken.None);
    }

我需要通过Entity Framework 7将变量文本传递给我的数据库，但我有问题。我怎么能这样做？
