Foreach inside Foreach C# - c#-4.0

Question

Saving the value the foreach inside foreach but the inner foreach will base on the outer foreach.
All i want is to save the two data but the inner foreach will base the value of Model2.SRL of outer foreach.
string[] _stpr = {"\r\n"};
string[] _slr = Model1.SRL.Split(_stpr, RemoveEmptyEntities);
string[] _chs = Model1.CHS.Split(_stpr, RemoveEmptyEntities);
foreach(string _s in _slr)
{
Model2.SRL = _s; // Test Value : SRL-1 // TotalCount = 5
Model2.DTL = "Detail";
Model2.CHS = string.empty;
functionToSave(ref transaction);
foreach(string _c in _chs)
{
Model2.SRL = _s; // will base on value from outer loop
Model2.CHS = _c; // Test Value : CHS-1
functionToSave(ref transaction);
}
}
commit();
When executing this, the result is that the last value of inner foreach will all column in the DB if multiple items.
Output Result:
SRL = SRL-1, CHS = CHS-1,
SRL = SRL-2, CHS = CHS-1,
SRL = SRL-3, CHS = CHS-1,
SRL = SRL-4, CHS = CHS-1,
SRL = SRL-5, CHS = CHS-1,
Expected Result:
SRL = SRL-1, CHS = CHS-1
SRL = SRL-2, CHS = CHS-2
SRL = SRL-3, CHS = CHS-3
SRL = SRL-4, CHS = CHS-4
SRL = SRL-5, CHS = CHS-5

Answer 1

You're focussing very much on mechanism rather than relying on the framework to do the drudgery for you.
This looks like a good use case for Zip. Assuming you have a using System.Linq; directive above this code:
string[] _stpr = {"\r\n"};
string[] _slr = Model1.SRL.Split(_stpr, RemoveEmptyEntities);
string[] _chs = Model1.CHS.Split(_stpr, RemoveEmptyEntities);
int _counter = 0;
foreach(var _s in _slr.Zip(_chs, (first,second) => new { first, second })
{
Model2.SRL = _s.first;
Model2.DTL = "Detail";
Model2.CHS = _s.second;
}
commit();
You may be able to improve this further. E.g. you seem to have a single Model2 instance that's reused each time through the loop. I'd have expected something like:
_slr.Zip(_chs, (first,second) => new WhateverModel2Is
{ SRL = first, CHS = second, DTL = "Detail" })
And be working with those instances each time through the loop.

Answer 2

Found the answer. I just added the incremental counter per row since it was an Array.
string[] _stpr = {"\r\n"};
string[] _slr = Model1.SRL.Split(_stpr, RemoveEmptyEntities);
string[] _chs = Model1.CHS.Split(_stpr, RemoveEmptyEntities);
int _counter = 0;
foreach(string _s in _slr)
{
Model2.SRL = _s; // Test Value : SRL-1 // TotalCount = 5
Model2.DTL = "Detail";
Model2.CHS = _chs[_counter];
_counter++;
}
commit();
