UpdatedOn Spalt von Datentyp datetime und es zeigt meine HTML-Tabelle wie 10-09-1992/12.00 .... Aber ich will wie 10-09-1992 nur Datum zeigen, was soll ich tun?

ist hier mein HTML-Tabelle

public string LoadDealHistory(DealHistory aDealhistory) 
{ 
     StringBuilder html = new StringBuilder(); 

     try { 
      using (DealTranctionGateway dealTranctionGateway = new DealTranctionGateway()) 
      { 
       DataTable dt = new DataTable(); 
       dt = dealTranctionGateway.LoadDealHistory(aDealhistory); 

       string dealHistory = ""; 

       if (dt.Rows.Count > 0) 
       { 
        html.Append("<table class='table table-bordered'>"); 
        html.Append("<thead>"); 
        html.Append("<tr>"); 
        html.Append("<th>S.No</th>"); 
        html.Append("<th>FieldType</th>"); 
        html.Append("<th>OldValue</th>"); 
        html.Append("<th>NewValue</th>"); 
        html.Append("<th>Full Name</th>"); 
        html.Append("<th>UpdateOn</th>"); 
        html.Append("</thead>"); 
        html.Append("</tr>"); 

        for (int i = 0; i < dt.Rows.Count; i = i + 1) 
        { 
         int sNo = i + 1; 
         html.Append("<tr>"); 
         html.Append("<td>" + sNo + "</td>"); 
         html.Append("<td>" + dt.Rows[i]["field"] + "</td>"); 
         html.Append("<td>" + dt.Rows[i]["old"] + "</td>"); 
         html.Append("<td>" + dt.Rows[i]["new"] + "</td>"); 
         html.Append("<td>" + dt.Rows[i]["Name"] + "</td>"); 
         html.Append("<td>" + dt.Rows[i]["UpdatedOn"] + "</td>"); 
         html.Append("</tr>"); 
        } 

        html.Append("</tbody>"); 
        html.Append("</table>"); 
       } 
      } 
     } 
     catch (Exception ex) 
     { 
     } 

     return html.ToString(); 
    } 
} 

Answer 1

Aktualisiert:

dies versucht:

string updateOn = ""; 
updateOn = ((DateTime)dt.Rows[i]["UpdatedOn"]).ToString("dd-MM-yyyy", CultureInfo.InvariantCulture); 
html.Append("<td>" + updateOn + "</td>"); 

ODER

können Sie verwenden Format Datetime in SQL:

Mehr Format at here.

In Ihrem Fall sollte es Stil 105 verwenden.

SELECT replace(convert(NVARCHAR, UpdatedOn, 105), ' ', '-') 

Answer 2

Select convert(date,getdate()) 

Answer 3

Sie es in einem String umwandeln können wie:

dt.Rows[i]["UpdatedOn"].ToString("dd-MM-yyyy") 

Keine Notwendigkeit für jegliche Änderungen auf SQL Server-Seite, Datumsformat ist ein Front-End-Problem.
