我的程序有一个问题:GC执行垃圾回收时，我的程序总是在一个函数崩溃，这个函数之前被主流调用过几次
崩溃，此函数的第一行是 GC.Collect()。函数的主要操作是向串行端口发送一些字节并从
同一个串口(发送和接收字节都在256字节以下)每次调用GC.Collect()是为了定位崩溃点，在
发行版。
我不知道确切的原因，但我知道程序崩溃的确切功能。所以，我必须在函数调用期间禁用GC或暂停GC。
我该怎么做？
我们将不胜感激!
真诚的， 机智果

最佳答案
GC 中的崩溃(非异常)意味着非托管(即 C++-CLR、不安全或非 .NET)代码已损坏堆。检查您的非 .NET 代码是否存在潜在问题!特别是 D:\jizg\NSIISys\bin\Debug .NET 中的那些文件？如果不是，他们对我来说看起来很可疑。
关于c# - 当 GC 执行垃圾收集时我的程序崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/1616716/
