c# - Using Zip to combine 3 strings instead of 2 -

i'm writing function add new nodes xml file, created 2 list<string> , combined them following

var firsttext = firstlist; var secondtext = secondlist; var alltext = firsttext.zip(secondtext, (t1, t2) => new { firstword = t1, secondword = t2 }); foreach (var tt in alltext) {     xml.writestartelement(tt.firstword);     xml.writevalue(tt.secondword);     xml.writeendelement(); } 

to add this

<force>true</force> <auto>false</auto> 

right want combine 3 strings instead of 2 writing this

xml.writestartelement(tt.firstword); xml.writestartelement(tt.secondword); xml.writevalue(tt.thirdword); xml.writeendelement(); xml.writeendelement(); 

so xml like

<settings>   <force>true</force> </settings> <settings>   <auto>true</auto> </settings> 

how can such thing?

just call .zip again:

var alltext = firsttext.zip(secondtext, (t1, t2) => new { firstword = t1, secondword = t2 });                        .zip(values, (t12, v) => new                             { firstword = t12.firstword,                               secondword = t12.secondword,                              thirdword = v });
