我正在寻找一些关于如何使用 Azure SDK 在 Azure 表存储中存储和检索数据的示例或文档。

我将 C# 与 .NET 4.5 框架一起使用。

我在这里找到了https://www.windowsazure.com/en-us/develop/net/how-to-guides/table-services/文档。

那个部分：

// Create the CloudTable object that represents the "people" table.
CloudTable table = tableClient.GetTableReference("people");

// Create a new customer entity.
CustomerEntity customer1 = new CustomerEntity("Harp", "Walter");
customer1.Email = "Walter@contoso.com";
customer1.PhoneNumber = "425-555-0101";

// Create the TableOperation that inserts the customer entity.
TableOperation insertOperation = TableOperation.Insert(customer1);

// Execute the insert operation.
table.Execute(insertOperation);

不再可用。

有人知道如何使用 .NET 4.5 做到这一点吗？

最好的祝福

这段代码工作正常。虽然文档提到了 2.0 版，但这指向的是存储 SDK 的版本，而不是 .NET 的版本。

编辑：

为了获得 GetTableReference 方法，您需要执行以下操作：

  • 参考 Microsoft.WindowsAzure.Storage.dll 版本 2.0.0.0 或更高版本（通过 NuGet Install-Package WindowsAzure.Storage：）
  • 添加以下命名空间：
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Auth;
using Microsoft.WindowsAzure.Storage.Table;
  • 初始化存储帐户和表客户端。
var account = new CloudStorageAccount(...);
var tableClient = account.CreateCloudTableClient();

这是我的表存储管理器类，我使用的是 .NET 4.5

public class TableStorageManager
{
    private CloudTableClient TableClient;
    private CloudTable Table;

    #region Sigleton implementation

    public TableStorageManager(string tablename)
    {
        TableClient = StorageFactory.GetCloudStorageAccount().CreateCloudTableClient();
        Table = TableClient.GetTableReference(tablename);
        //var ctx = TableClient.GetTableServiceContext();

        Table.CreateIfNotExists();
    }

    #endregion

    public void InsertAnyEntity<T>(T entity)
    {
        var translatedEntity = Helper.ConvertToDictionaryEntity<T>(entity);
        InsertEntity<DictionaryEntity>(translatedEntity);
    }
    public void InsertEntity<T>(T entity) where T : ITableEntity
    {
        Table.Execute(TableOperation.InsertOrReplace(entity));
    }

    public IEnumerable<T> ExecuteQuery<T>(TableQuery<T> query) where T : class, ITableEntity, new()
    {
        return Table.ExecuteQuery(query);
    }

    public IEnumerable<T> GetEntities<T>(String partitionKey, Int32 noOfRecords ) where T : ITableEntity, new()
    {
        var query = new TableQuery<T>().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, partitionKey));
        var result = Table.ExecuteQuery(query).Take(noOfRecords).ToList();
        return result;
    }

    public T GetEntity<T>(String partitionKey, String rowKey) where T : class, ITableEntity, new()
    {
        var retrieveOperation = TableOperation.Retrieve<T>(partitionKey, rowKey);

        // Execute the retrieve operation.
        var retrievedResult = Table.Execute(retrieveOperation);
        return retrievedResult.Result as T;
    }

    public Boolean DeleleEntity<T>(String partitionKey, String rowKey) where T : class, ITableEntity, new()
    {
        TableOperation retrieveOperation = TableOperation.Retrieve<T>(partitionKey, rowKey);

        // Execute the operation.
        var retrievedResult = Table.Execute(retrieveOperation);

        // Assign the result to a CustomerEntity.
        var deleteEntity = (T)retrievedResult.Result;

        // Create the Delete TableOperation.
        if (deleteEntity != null)
        {
            TableOperation deleteOperation = TableOperation.Delete(deleteEntity);

            // Execute the operation.
            Table.Execute(deleteOperation);
        }

        return true;
    }

    public Boolean UpdateEntity<T>(String partitionKey, String rowKey) where T : class, ITableEntity, new()
    {
        TableOperation retrieveOperation = TableOperation.Retrieve<T>(partitionKey, rowKey);

        // Execute the operation.
        TableResult retrievedResult = Table.Execute(retrieveOperation);

        // Assign the result to a CustomerEntity object.
        var updateEntity = (T)retrievedResult.Result;

        if (updateEntity != null)
        {
            // Create the InsertOrReplace TableOperation
            TableOperation updateOperation = TableOperation.Replace(updateEntity);

            // Execute the operation.
            Table.Execute(updateOperation);
        }

        return true;
    }

    public Boolean UpdateEntity<T>(T entity) where T : class, ITableEntity, new()
    {
        Boolean isUpdate = false;
        try
        {
            // Create the InsertOrReplace TableOperation
            TableOperation updateOperation = TableOperation.Replace(entity);

            // Execute the operation.
            Table.Execute(updateOperation);
            isUpdate = true;
        }
        catch (Exception ex)
        {
            isUpdate = false;
        }

        return isUpdate;
    }
}
