In C#, if I want to deterministically clean up non-managed resources, I can use the "using" keyword. But for multiple dependent objects, this ends up nesting further and further:
using (FileStream fs = new FileStream("c:\file.txt", FileMode.Open))
{
using (BufferedStream bs = new BufferedStream(fs))
{
using (StreamReader sr = new StreamReader(bs))
{
// use sr, and have everything cleaned up when done.
}
}
}
In C++, I'm used to being able to use destructors to do it like this:
{
FileStream fs("c:\file.txt", FileMode.Open);
BufferedStream bs(fs);
StreamReader sr(bs);
// use sr, and have everything cleaned up when done.
}
Is there a better way in C# to do this? Or am I stuck with the multiple levels of nesting?
