C Sharp (C#) - File IO

Identify the error in the following code snippet that uses a using statement with a file stream:

using (FileStream fs = new FileStream("data.txt", FileMode.Open))
    byte[] buffer = new byte[100];
    fs.Read(buffer, 0, buffer.Length);

AFileMode.Open is invalid for reading

BMissing braces {} after the using statement

CBuffer size should be 0

DFileStream cannot be used with using

Step-by-Step Solution

Solution:

Step 1: Check using statement syntax
The using statement requires braces {} to define the scope of the resource usage.
Step 2: Analyze the code block
Without braces, only the first line after using is considered inside the block. The buffer declaration and read call are outside, causing a compile error.
Final Answer:
Missing braces {} after the using statement -> Option B
Quick Check:
Using needs braces for multiple statements [OK]

Quick Trick: Always use braces {} after using for multiple lines [OK]
