# AL0035 - Use GetFullyQualifiedName/GetMetadataName()

> Replace ToDisplayString() with semantic name extensions

Source: [AL0035UseToDisplayStringExtensionsAnalyzer.cs](https://github.com/ANcpLua/ANcpLua.Analyzers/blob/main/src/ANcpLua.Analyzers/Analyzers/AL0035UseToDisplayStringExtensionsAnalyzer.cs)

## Description

Using `ToDisplayString()` with format options is verbose. ANcpLua.Roslyn.Utilities provides clearer alternatives for common symbol name formats.

## Bad Code

```csharp theme={null}
using Microsoft.CodeAnalysis;

// Verbose display format
var fqn = symbol.ToDisplayString(SymbolDisplayFormat.FullyQualifiedFormat);
var metadata = symbol.ToDisplayString(
    new SymbolDisplayFormat(typeQualificationStyle: ...));
```

## Good Code

```csharp theme={null}
using ANcpLua.Roslyn.Utilities;

// Clear intent
var fqn = symbol.GetFullyQualifiedName();
var metadata = symbol.GetMetadataName();
```

## Properties

* **Category**: Usage
* **Severity**: Info
* **Enabled by default**: True
* **Code fix available**: False

## Configuration

```editorconfig theme={null}
dotnet_diagnostic.AL0035.severity = suggestion
```

## Notes

* `GetFullyQualifiedName()` - returns `global::Namespace.Type` format
* `GetMetadataName()` - returns assembly metadata name format
* Both are common operations in Roslyn analyzer development
