堆/缓冲区溢出异常 [英] Heap / buffer overflow exception

问题描述

很好奇，有没有人遇到C＃中的堆/缓冲区溢出异常？

Just curious, Is there or has anyone ever come across a heap / buffer overflow exception in C#?

推荐答案

您可能会以不安全的代码在C＃中导致缓冲区溢出。例如：

You can cause a buffer overflow in C# in unsafe code. For example:

public unsafe struct testo
{
    public int before;
    public fixed int items[16];
    public int after;
}

testo x = new testo();
x.after = 1;
for (int i = 0; i <= 16; ++i)
{
    unsafe
    {
        x.items[i] = 99;
     }
}
Console.WriteLine(x.after);

以上将打印 99，因为它溢出了缓冲区。

The above will print "99" because it overflowed the buffer.

缺少不安全的代码，我不知道有什么方法可以导致不会触发异常的缓冲区溢出。

Absent unsafe code, I do not know of any way to cause a buffer overrun that doesn't trigger an exception.
