Generics

TypeSharp maps C# generic collections and types to their TypeScript equivalents.

Collection mappings

C#	TypeScript
List<T>	T[]
IList<T>	T[]
IEnumerable<T>	T[]
ICollection<T>	T[]
IReadOnlyList<T>	readonly T[]
HashSet<T>	T[]
ISet<T>	T[]
Dictionary<K, V>	Record<K, V>
IDictionary<K, V>	Record<K, V>
IReadOnlyDictionary<K, V>	Record<K, V>

Generic type parameters

Generic type parameters on classes and records are preserved in the TypeScript output.

ApiResponse.cs — typesharp

apiResponse.ts

[TypeSharp]
public class ApiResponse<T>
{
    public bool Success { get; set; }
    public string? Message { get; set; }
    T? Data { get; set; }
    public List<string> Errors { get; set; }
}

/**
