如何通过使用 VisualC # 绑定到 ArrayList 对象或结构的 DataGrid 控件

public class guitar
{
	private string make;
	private string model;
	private short year;
	
	public guitar()
	{
	}

	public guitar(string Make, string Model, short Year)
	{
	    make=Make;
	    model=Model;
	    year=Year;
	}

	public string Make 
	{
		get 
		{ 
			return make; 
		}
		set 
		{
			make = value; 
		}
	}
	
	public string Model 
	{
		get 
		{ 
			return model; 
		}
		set 
		{
			model = value; 
		}
	}

	public short Year 
	{
		get 
		{ 
			return year; 
		}
		set 
		{
			year = value; 
		}
	}
}
					

private ArrayList al = new ArrayList();	
private CurrencyManager currencyManager=null;	
					

al.Add (new guitar("Gibson", "Les Paul", 1958));
al.Add (new guitar("Fender", "Jazz Bass", 1964));
al.Add (new guitar("Guild", "Bluesbird", 1971));
				
currencyManager = (CurrencyManager)dataGrid1.BindingContext[al];
	
dataGrid1.DataSource=al;
					

currencyManager.Position++;
					

currencyManager.Position--;
					

currencyManager.Position = 0;
					

currencyManager.Position = al.Count - 1;
