使用 Azure.Data.Tables.TableClient 检查 Azure 存储表中是否存在一行

Question

I'm using Azure.Data.Tables.TableClient (also looked at Azure.Data.Tables.TableServiceClient ).

I want to check if a record exists in the Azure Table given a specific Partition Key and Row Key. Calling the TableClient.GetEntity<T> throws an exception if it gets 404 from the server rather than returning null.

I've searched on SO and there is one solution available but it uses the older CloudTable .

I've tried looking at the TableServiceClient options but so far haven't had any success finding a good solution that doesnt require catching the exception.

You can probably use Query and specify your query as PartitionKey eq 'partition-key-value' and RowKey eq 'row-key-value' .

If the entity does not exist, you will receive an empty array back instead of error. If the entity exists, you will receive an array with just 1 entity.
