CosmosDb使用LINQ查询选择多个值

using Microsoft.Azure.Cosmos;
using System.Linq;

string connectionString = "your_connection_string";
CosmosClient cosmosClient = new CosmosClient(connectionString);

string databaseName = "your_database_name";
string containerName = "your_container_name";
Database database = await cosmosClient.GetDatabase(databaseName);
Container container = await database.GetContainer(containerName);

IQueryable<Item> query = container.GetItemLinqQueryable<Item>()
    .Where(item => item.Property1 == value1 && item.Property2 == value2)
    .Select(item => new { item.Property3, item.Property4 });

FeedIterator<Item> resultSetIterator = query.ToFeedIterator();
while (resultSetIterator.HasMoreResults)
{
    FeedResponse<Item> response = await resultSetIterator.ReadNextAsync();
    foreach (Item item in response)
    {
        // 处理查询结果
        // item.Property3 和 item.Property4 是选择的多个值
    }
}
