Example:

StreamReader sr = new StreamReader("path.txt");
sr.Dispose();
string line = sr.ReadLine();

Trying to use an object after disposing of it.

Solution:

This exception occurs when you try to access a disposed object. Always check if an object is disposed before using it, or ensure proper order of operations.


if(sr != null && !sr.EndOfStream) {
    string line = sr.ReadLine();
}
