c# – 字符串长度超过32768个字符时的Azure存储异常
作者:互联网
我的应用程序是ASP.NET Core 1.0 Web API.如果我的控制器返回一个小字符串,一切正常.但是如果字符串长度超过32768,我收到以下错误消息:
--- End of stack trace previous location where exception was thrown ---

这是我的控制器:
[HttpGet]
[Produces("plain/text")]
public async Task<IActionResult> GetData()
{
return this.Ok(this.GetResponse());
}
private string GetResponse()
{
string retVal = string.Empty;
for (int i = 0; i < 32769; i++)
{
retVal = retVal + "a";
}
return retVal;
}
完整的错误消息:

我想返回长度超过32768的字符串.
有什么建议吗?
解决方法:
您遇到字符串属性类型(source)的Azure存储限制:
Edm.String (String) – A UTF-16-encoded value. String values may be up to 64 KB in size.
因为UTF-16编码的字符串需要2个字节来存储字符,所以最大字符串长度为32768个字符.
