在C#中创建一个简单的名称值映射器类

using System.Collections.Generic;

public class NameValueMapper
{
    private Dictionary<string, object> _mappings;

    public NameValueMapper()
    {
        _mappings = new Dictionary<string, object>();
    }

    public void AddMapping(string name, object value)
    {
        _mappings.Add(name, value);
    }

    public object GetValue(string name)
    {
        if (_mappings.ContainsKey(name))
        {
            return _mappings[name];
        }
        else
        {
            throw new KeyNotFoundException($"Mapping for '{name}' not found.");
        }
    }
}
