C 14 introduces a new capability allowing the use of unbound generic types as arguments to nameof
. For example:
Console.WriteLine(nameof(List<>)); // Output: "List"
Previously, only closed generic types (e.g., List<int>
) were permitted. This enhancement simplifies reflection and dynamic type handling in large-scale applications.
You Should Know:
1. Practical Use Cases
- Reflection & Dynamic Code Generation:
Type openGeneric = typeof(List<>); Console.WriteLine(nameof(List<>)); // Helps avoid hardcoding strings
- Logging & Debugging:
Debug.WriteLine($"Processing type: {nameof(Dictionary<,>)}");
2. Linux & Windows Commands for .NET Developers
- Compile & Run C 14 Code (Linux):
dotnet new console -n CSharp14Demo cd CSharp14Demo dotnet add package Microsoft.Net.Compilers.Toolset --version 4.8.0 dotnet run
- Check .NET SDK Version:
dotnet --version
- Windows PowerShell (Check Installed Runtimes):
dotnet --list-runtimes
3. Advanced Example: Dynamic Type Resolution
var typeName = nameof(List<>); Type genericType = Type.GetType($"System.Collections.Generic.{typeName}`1"); Console.WriteLine(genericType?.FullName);
4. Expected Performance Impact
- No runtime overhead—resolved at compile time.
- Reduces magic strings in reflection-heavy code.
Prediction
This feature will be widely adopted in ORMs (e.g., Entity Framework) and serialization libraries to simplify generic type handling.
What Undercode Say
C continues to evolve, bridging gaps between static and dynamic typing. This update, while subtle, enhances meta-programming. For Linux/.NET interoperability, consider these commands:
List all dotnet processes (Linux) ps aux | grep dotnet Monitor .NET app memory usage top -p $(pgrep -f "MyApp.dll")
Expected Output:
List System.Collections.Generic.List`1[bash]
