我的应用程序是 ASP.NET Core 1.0 Web API。如果我的 Controller 返回一个小字符串,则一切正常。但如果字符串长度超过 32768,我会收到以下错误消息:
--- End of stack trace previous location where exception was thrown ---

这是我的 Controller :
[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;
}

我想返回比 32768 长的字符串。
有什么建议吗?
最佳答案
您遇到了字符串属性类型 ( 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.
由于 UTF-16 编码的字符串需要 2 个字节来存储一个字符,因此最大字符串长度为 32768 个字符。
关于c# - 当字符串长度超过 32768 个字符时,Azure 存储异常,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/42924571/
