SqlDataSource 및 콤마 또는 공백이 검색 문자열의 일부인 경우 "포함"

Question

코드 숨김으로 C#을 사용하여 Asp.net에 응용 프로그램을 작성하고 있습니다. SqlDataSource를 필터링하기위한 사용자 장소 정보의 텍스트 상자 ("txtNameSearch")와 해당 SQL 데이터를 기반으로 채우는 gridview가 있습니다. 사용자가 상자에 쉼표 나 공백을 입력하면 SqLDataSource에 예외 오류가 발생합니다. 데이터베이스에이 필드에 구두점이 허용되어 있기 때문에 이런 종류의 검색을 허용하고 싶습니다.

내가 텍스트 상자를 복용하고 쉼표 또는 공간을 확인하여 뒤에 C# 코드에서이 문제를 해결 :

<asp:SqlDataSource ID="Sql_NameList" runat="server" ConnectionString='<%$ ConnectionStrings:Recorder %>' 
     SelectCommand="SELECT [Name], [Address1], [Address2], [CSZ], [PersonID] FROM [People] WHERE (CONTAINS([Name], @Name))"> 

     <SelectParameters> 
      <asp:ControlParameter ControlID="txtNameSearch" PropertyName="Text" Name="Name" Type="String"> 
      </asp:ControlParameter> 
     </SelectParameters> 

    </asp:SqlDataSource> 

다음은 예외 텍스트입니다. 존재하는 경우 따옴표가 텍스트 주위에 추가되고 쿼리가 쉼표 나 공백을 막지 않습니다. 아래 코드 참조 :

 if (txtNameSearch.Text.Contains(",") || txtNameSearch.Text.Contains(" ")) 
      { 
      if (txtNameSearch.Text.Contains('"')) 
       { 

       } 
      else 
       { 
       txtNameSearch.Text = '"' + txtNameSearch.Text + '"'; 
       } 
      }
