Call Azure Queue get "The remote server returned an error: (400) Bad Request."

這幾天開始研究Windows Azure， 在使用Azure Queue 的時候，CreateInfNotExists 總是抛出異常 "The remote server returned an error: (400) Bad Request."

查了一下，原因盡然是Queue的名字是有要求的：

Every queue within an account must have a unique name. The queue name must be a valid DNS name, and cannot be changed once created. Queue names must confirm to the following rules:

A queue name must start with a letter or number, and can only contain letters, numbers, and the dash (-) character.

The first and last letters in the queue name must be alphanumeric. The dash (-) character cannot be the first or last character. Consecutive dash characters are not permitted in the queue name.

All letters in a queue name must be lowercase.

A queue name must be from 3 through 63 characters long.

注意第三條，所有字母要小寫。

把這一句 var queue = queueClient.GetQueueReference(“Regesp”);  改成 var queue = queueClient.GetQueueReference(“regesp”); 就解決問題了。
