日期的比較?

[yyf888yyf]

以下代碼﹕
if(("2005/03/31").Equals(System.DateTime.Now.Year+"/"+System.DateTime.Now.Month+"/"+System.DateTime.Now.Day.ToString()))
{
Response.Write("y");
}
else
{
Response.Write("n");
}
怎么才能相等?

[sskset]

if(("2005/03/31").Equals(System.DateTime.Now.Year.ToString()+"/"+"0"+System.DateTime.Now.Month.ToString()+"/"+System.DateTime.Now.Day.ToString()))
{
Response.Write("y");
}
else
{
Response.Write("n");
}

[sskset]

System.DateTime.Now.Month
取出來是 3
但是前面的字符串是 03
所以不相等

[sskset]

個人建議用
if(("2005/03/31").Equals(DateTime.Now.ToString("yyyy/MM/dd")))
{
Response.Write("y");
}
else
{
Response.Write("n");
}
