c# - Azure:如何在表存储中保存 IDictionary？

Question

我有一个带有 IDictionary 的类(class)。该对象的大小不固定为任何特定大小。这个想法是拥有我的对象的动态模式。我想将此对象存储在 TableStorage 中。我怎样才能做到这一点？在我的对象中再次使用 IDictionary 后，如何从存储中检索此信息？

谢谢!!

DynamicTableEntity需要IDictionary<string,EntityProperty>作为参数。

此代码在 LinqPad 中执行:

void Main()
{
var account = "";
var key = "";
var tableName = "";

var storageAccount = GetStorageAccount(account, key);
var cloudTableClient = storageAccount.CreateCloudTableClient();
var table = cloudTableClient.GetTableReference(tableName);

var partitionKey = "pk";
var rowKey = "rk";

//create the entity
var entity = new DynamicTableEntity(partitionKey, rowKey, "*", 
    new Dictionary<string,EntityProperty>{
            {"Prop1", new EntityProperty("stringVal")},
            {"Prop2", new EntityProperty(DateTimeOffset.UtcNow)},
        });

//save the entity
table.Execute(TableOperation.InsertOrReplace(entity));

//retrieve the entity
table.Execute(TableOperation.Retrieve(partitionKey,rowKey)).Result.Dump();
}

static CloudStorageAccount GetStorageAccount(string accountName, string key, bool useHttps = true)
{
var storageCredentials = new StorageCredentials(accountName, key);
var storageAccount = new CloudStorageAccount(storageCredentials, useHttps: useHttps);
return storageAccount;
}
