Question

i am here to ask if there are any ways to put variables inside “@” Strings in C#.
Such that the id in the following code, can be changeable.

        string xml = @"
        <S>
          <child id='1'/>
          <child id='2'>
            <grandchild id='3' />
            <grandchild id='4' />
          </child>
        </S>";

Answer 1

take a look at the string.Format method

var result = string.Format(@"<S> 
          <child id='{0}'/> 
          <child id='{1}'> 
            <grandchild id='{2}' /> 
            <grandchild id='{3}' /> 
          </child> 
        </S>", id1, id2, id3, id4);
