Azure Blob文件名中的模式搜索 [英] Pattern search in Azure blob file names

问题描述

我正在尝试搜索与我的搜索模式匹配的文件. /span>

I am trying to search files that match my search pattern.

static void ListBlobsInFolder() {
            var account = <MyStorageAccount>
            var blobClient = account.CreateCloudBlobClient();
            var containerName = "importcontainer";
            var folderName = "subfolder";
            var container = blobClient.GetContainerReference(containerName);
            var query = container.ListBlobs(prefix: folderName, useFlatBlobListing: true, blobListingDetails: BlobListingDetails.None);
            foreach(var item in query) {
                Console.WriteLine(item.Uri.Segments.Last());
            }
        }

This gets me the list of files present in the subfolder.

有没有一种方法可以返回仅与模式匹配的文件.示例我想检索包含"abc"的文件名.在里面.

Is there a way to return the files that only match a pattern. Example I want to retrieve file names that contains "abc" in it.

在Azure中有可能吗?

Is this possible in Azure ?

推荐答案

唐加，

您应该能够使用LINQ查询来获取具有特定模式的文件的结果.您可以使用布尔方法Contains("abc").例如:

You should be able to use a LINQ query for getting the results of files with a specific pattern. You can use boolean method Contains("abc").  For example:

if(item.Uri.Segments.Last().Contains("abc"))
{
    Console.WriteLine(item);
}

有关如何使用此方法的更多详细信息，我建议使用以下LINQ参考指南:

For further details on how you can use this method, I would recommend the following LINQ reference guide: https://docs.microsoft.com/en-us/dotnet/api/system.linq.enumerable.contains?view=netframework-4.7.2
