我正在使用新的Web应用程序,并且试图连接到现有的Azure表存储。
using System.Web.Mvc;
using Microsoft.Azure;
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Table;
using System;
namespace WebApplication3.Controllers
{
public class GetEmailAddressesController : Controller
{
public ActionResult Address()
{
string emails = "";
// Parse the connection string and return a reference to the storage account.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("________"));
// Create the table client.
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
CloudTable table = tableClient.GetTableReference("experimentsEmailAddresses");
// Construct a table query.
TableQuery<TableData> query = new TableQuery<TableData>();
foreach (TableData entity in table.ExecuteQuery(query))
{
emails += entity.Email + ";";
}
ViewBag.Message = " " + emails;
return View();
}
}
}
代码将编译,但是当我在调试模式下运行时,我得到一个错误:
System.ArgumentNullException:'值不能为null。参数名称:connectionString'
尽管我从Azure的Access键复制了连接字符串,但我的连接字符串无效。
什么是最佳解决方案?

我认为您应该更改:
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("________"));
收件人:
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("StorageConnectionString"));
希望有帮助!

我改变了
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("StorageConnectionString"));
到
CloudStorageAccount storageAccount = cloudStorageAccount.Parse("StorageConnectionString");
它似乎运行完美。
