Are Nested Using Statements Necessary in C# File Comparison?

Discussion on nested Using statements in C#

Recently, a developer used nested using statements when writing an exact match comparison program for file content:

<code class="language-csharp">using (StreamReader outFile = new StreamReader(outputFile.OpenRead()))
{
    using (StreamReader expFile = new StreamReader(expectedFile.OpenRead()))
    {
        // ...文件比较逻辑...
    }
}</code>

The

code was functional, but the developer had questions about the necessity of nested using statements and explored other methods.

An improvement suggestion is to merge using statements and avoid nested curly braces:

<code class="language-csharp">using (StreamReader outFile = new StreamReader(outputFile.OpenRead()))
using (StreamReader expFile = new StreamReader(expectedFile.OpenRead()))
{
    // ...文件比较逻辑...
}</code>

This simplified approach eliminates nested using statements while maintaining the original functionality. This approach makes the code more concise and readable.
