想使用OAuth2和.NET 4.5框架构建一个GoogleBigQueryC#ASP.NET应用程序

Install-Package Google.Apis.Bigquery.v2 -Pre
Install-Package Google.Apis.Authentication.OAuth2 -Version 1.2.4696.27634

Install-Package Google.Apis -Pre
Install-Package Google.Apis.Auth -Pre

将相关的“usings”放在代码隐藏文件“default.aspx.cs”中：

using System;
using System.Collections.Generic;
using System.IO;
using System.Threading;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Bigquery.v2;
using Google.Apis.Bigquery.v2.Data;

namespace BigQueryDemoApp
{
    public partial class _Default : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            UserCredential credential;
            FileStream stream;

            using (stream = new FileStream(
                    Server.MapPath("~/client_secrets.json"),
                    FileMode.Open, FileAccess.Read)
                )
            {
                GoogleWebAuthorizationBroker.Folder =
                    "Tasks.Auth.Store";
                credential = GoogleWebAuthorizationBroker.
                    AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    new[] { BigqueryService.Scope.Bigquery },
                    "user", CancellationToken.None).Result;
            }

            // Initialize the service.
            var Service = new BigqueryService(
                new BaseClientService.Initializer()
                {
                    HttpClientInitializer = credential,
                    ApplicationName = "BigQueryDemo"
                }
            );
        }
    }
}

将这个特定的页面设置为项目开始页面

APIS & auth -> Credentials -> CREATE NEW CLIENT ID

确保正确地映射到客户端。使用Server.MapPath
