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

这几天开始研究Windows Azure， 在使用Azure Queue 的时候，CreateInfNotExists 总是抛出异常 "The remote server returned an error: (400) Bad Request."

const string RegespStorageConnectionStringKey = "RegespStorageConnectionString";

var storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting(RegespStorageConnectionStringKey));

var queueClient = storageAccount.CreateCloudQueueClient();

var queue = queueClient.GetQueueReference(“Regesp”);

queue.CreateIfNotExists();

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;

margin: 0em;
}
.csharpcode .lnum { color: #606060; }

查了一下，原因尽然是Queue的名字是有要求的：

Queue Names （http://msdn.microsoft.com/en-us/library/windowsazure/dd179349.aspx）

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:

1. A queue name must start with a letter or number, and can only contain letters, numbers, and the dash (-) character.
2. 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.
3. All letters in a queue name must be lowercase.
4. A queue name must be from 3 through 63 characters long.

注意第三条，所有字母要小写。

把这一句 var queue = queueClient.GetQueueReference(“Regesp”);  改成 var queue = queueClient.GetQueueReference(“regesp”); 就解决问题了。
