c# - join two dictionary values based on key and check condition on value field -

how merge 2 dictionay dictionary structure

first dictionary:

key: key1   value: {100,name1,address1, address2, address3, address4, address5}          {100,name2,address1, address2, address3, address4, address5}  

second dictionary:

key: key1   value: {100,name1,field1, field2, field3, field4, field5}           {101,name1,field1, field2, field3, field4, field5}    

here have check value field list of string array. in above case in both dictionary have common value 100 , name1 so.
expected result:

key: key1   value: {100,name1,address1, address2, address3, address4, address5,field1, field2, field3, field4, field5} 

hi below approach. var final = new dictionary>();

foreach (var item in _record1) { var key = item.key;

            list<string[]> first = _record1[key];              list<string[]> second = _record2[key];               foreach (var in first)              {                  foreach (var b in second)                  {                      if (a[0] == b[0] && a[1] == b[1])                      {                          // operation                          // add items final                                                }                  }              }          } 

i able desired result looking approach.
