c# - BufferNotEnough 无法创建 SSL/TLS 安全通道

Question

有时我们会收到错误“请求已中止:无法创建 SSL/TLS 安全通道..”我试图调查这个问题，我得到的跟踪日志是:

System.Net Information: 0 : [4356] InitializeSecurityContext(In-Buffers count=2, Out-Buffer length=0, returned code=**BufferNotEnough**).
System.Net Error: 0 : [4356] Exception in HttpWebRequest#37434592:: - The request was aborted: Could not create SSL/TLS secure channel..
System.Net Error: 0 : [4356] Exception in HttpWebRequest#37434592::EndGetRequestStream - The request was aborted: Could not create SSL/TLS secure channel..

对于这种情况，BufferNotEnough 是什么意思？

谢谢。

这似乎是 .NET 4.6.1 中 HttpWebRequest 中的一个错误 - 参见 https://connect.microsoft.com/VisualStudio/feedback/details/2777134/tls-1-2-handshake-error
