Code (C#)
<connectionStrings/>
<connectionStrings>
<add name="MyProjectDBConnection" connectionString="Data Source=.\SQLEXPRESS; AttacDbFilename=|DataDirectory|\MyProjectDB.mdf; Integrated Security=True; User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
ใส่ tag จะดีมากถ้าไม่ลำบากค่ะ
ลบตัว <connectionStrings/> ออกไป <connectionStrings/> มีได้ 1 section ต่อ webconfig 1 file
ยกเว้นว่าจะเพิ่มลงใน <location/> แยกแต่ path ค่ะ
