StringBuilder .ToString（）抛出OutOfMemory异常

Question

list is a string builder that includes a csv that I'm requesting from a website, toString() is crashing.

Exception of type 'System.OutOfMemoryException' was thrown. 

It's worth mentioning that my Microsoft.VsHub.Server.HttpHostx64 is using 5GB of memory, which wasn't the case before.

I tried the following:

• Check if I have WebCompanion to uninstall [I didn't]
• Tried to turn off BrowserLink in VS
• Restarted my machine

I have 3GB of free memory which should be enough to convert a 100MB string.

Answer 1

The reason is the virtual limit on StringBuilder. if you're not using stream, then do a partial read, read strings up to a certain size, then write them into your text, then empty the builder and repeat.
