Introduction:

In this article I am going to explain about how to comment code in asp.net,c#.net.

Description:

For commenting single line code in c#.net we are using // at the starting of the line. To comment multiline code we are using /* at the start and */ at the end. In ASP.Net we are using  <%--
At the start of the code and --%>  at the end of the code. Instead we can use the shortcut CTRL+K+C to comment both the C#.Net and Asp.Net code and CTRL+K+U for uncommenting the code.


Below is the sample commented code:

Single Line C#.Net code comment

//protected void Page_Load(object sender, EventArgs e)

MultiLine C#.Net code comment

/*protected void Page_Load(object sender, EventArgs e)
{
    SqlConnection sqlcon = new SqlConnection();
    SqlCommand cmd = new SqlCommand();
    cmd.CommandText = "Myprocedure";
    cmd.CommandType = CommandType.StoredProcedure;
}*/

ASP.NET Commented code:

<%--<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>--%>


We can comment javascript code using // or using <%-- --%>. But always use the second one to comment the javascript code. Since if u comment your javascript code using // and that commented code contains code for some non available elements in your page then it may through the error. So always use <%-- --%> to comment the javascript code as given below.

<%--function echo() {
    alert('Hello');
} --%>

Do you like this code. Then comment here or share with your friends. Or like our facebook page.
