日历System.Globalization.GregorianCalendar不支持由字符串表示的DateTime.

问题描述

在日期落在12点之后，我在检索日期时遇到了问题，例如:如果我从calander扩展器中单击:2013/2/7到2013年7月19日，会因为这个错误而把它扔给我:日历System.Globalization.GregorianCalendar中不支持该字符串表示的DateTime.

i am having problem with my retrieving of date after the date fall after 12. for example : if i click from the calander extender: 2/7/2013 to 19/july/2013 , is will throw it me with this error : The DateTime represented by the string is not supported in calendar System.Globalization.GregorianCalendar.

这是我的代码:

var format = "MM/dd/yyyy";
    DateTime one = DateTime.ParseExact(startdate, format, CultureInfo.InvariantCulture);
    DateTime two = DateTime.ParseExact(enddate, format, CultureInfo.InvariantCulture);



    if (two >= one)
    {
        SqlConnection conn = new SqlConnection("Data Source=""catalog="";Integrated Security=True");
        conn.Open();
        SqlCommand cmd = new SqlCommand("SELECT Name,CLass, NRIC, StallNo, AmountSpent ,TimeDate=convert(nvarchar,timedate,103)  FROM StudentTransactions WHERE TimeDate BETWEEN '" + one + "' AND '" + two + "'", conn);
        SqlDataReader reader = cmd.ExecuteReader();
        GridView1.DataSource = reader;
        GridView1.DataSourceID = null;
        GridView1.Visible = true;
        GridView1.DataBind(); 
        conn.Close();
   }

推荐答案

19/7/2013 不能使用 MM/dd/yyyy 格式解析为19 不是有效月份.
您可能要改用 dd/MM/yyyy .

19/7/2013 cannot be parsed using MM/dd/yyyy format as 19 is not a valid month.
You may want to use dd/MM/yyyy instead.
