SqlDataReader的GetDateTime格式 [英] SQLDataReader GetDateTime Format

问题描述

检查我下面的code：搜索结果

Check my code below:

HTML页：

<table width="100%" align="right" cellpadding="2" cellspacing="2" border="0" bgcolor="#EAEAEA">
    <tr align="center" style="background-color: yellow; color: black;">
        <th colspan="2">Fauzan</th>
        <th colspan="2">Febri</th>
    </tr>
    <tr align="left" style="background-color: gray; color: black;">
        <td>ID</td>
        <td>Number01</td>
        <td>TheDate</td>
        <td>Number02</td>
    </tr>
    <%=getWhileLoopData()%>
</table>

code背后：

Code Behind:

public string getWhileLoopData() 
{
 string htmlStr = "";
 SqlConnection thisConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString);
 SqlCommand thisCommand = thisConnection.CreateCommand();
 thisCommand.CommandText = "SELECT * FROM MyTable WHERE TheDate = @TheDate";
 thisCommand.Parameters.AddWithValue("@TheDate", txtDate.Text);

 thisConnection.Open();
 SqlDataReader reader = thisCommand.ExecuteReader();

 while (reader.Read()) {
     int id = reader.GetInt32(0);

     int Number01 = reader.GetInt32(1);
     DateTime TheDate = reader.GetDateTime(2);
     Decimal Number02 = reader.GetDecimal(3);

     //string Pass = reader.GetString(2);
     htmlStr += "<tr><td>" + id + "</td><td>" + Number01 + "</td><td>" + TheDate + "</td><td>" + Number02 + "</td></tr>";
 }

 thisConnection.Close();
 return htmlStr;
}

现在的问题是，我怎么能格式化数据读取器？像TheDate领域，从2014年6月18日12:00:00 AM'到'18 /月/ 2014年。也为'Number02'领域，我怎么可以格式化呢？就像从'0.829'变成'0.83'。搜索结果

The question is, how can i format the data reader? Like, "TheDate" field, from '6/18/2014 12:00:00 AM' to '18/Jun/2014'. Also for 'Number02' field, how can i format it? Like, from '0.829' become '0.83'.

推荐答案

您可以使用的ToString（）用的自定义日期和时间格式字符串

You can format datetime using ToString() with Custom Date and Time Format Strings

string strDate = TheDate.ToString("dd/MMM/yyyy");

您可以使用 Math.Round 以格式编号

Number02 = Math.Round(Number02, 2);

您可以直接格式化日期和数量正在制作的HTML字符串

You can directly format date and number in the html string you are making

htmlStr += "<tr><td>" + id + "</td><td>" + Number01 + "</td><td>" +
   TheDate.ToString("dd/MMM/yyyy") + "</td><td>" +  Math.Round(Number02, 2) + "</td></tr>";
