how to access a string array outside loop

Question

for (int z = 0; z < alParmValues.Count; z++)
{
   //string[] def;
   string[] asd = alParmValues[z].ToString().Split(',');//this is of type string.collections and u cant cast it to a arraylist or array 
   //if (HUTT.clsParameterValues.bCustomObj == false)

   string[] def = alMethSign[z].ToString().Substring(alMethSign[z].ToString().IndexOf('(') + 1, alMethSign[z].ToString().IndexOf(')') - (alMethSign[z].ToString().IndexOf('(') + 1)).Split(',');
}

I have to access both the string arrays outside the loop. Is there a better solution to this? I can't use an ArrayList or declare them as public so how can I access them?

Answer 1

To access something outside of a loop, just declare it outside of the loop, then work with it after your loop processing is done:

string[] arr = ...

for (int z = 0; z < alParmValues.Count; z++)
{
  // work with arr...
}

var item = arr[3]; // Accessed outside of loop.

However, there seem to be a few things wrong with your code. I'd recommend thinking a little bit more about the loop body and what you're trying to do there. Consider this line, for example:

for (int z = 0; z < alParmValues.Count; z++)
{
  // ...
  string[] asd = alParmValues[z].ToString().Split(',');

  // There aren't any more references to asd after this point in the loop,
  //   so this assignment serves no purpose and only keeps its last assigned
  //   value.
}

This assignment is pointless; every time you go through the loop, you just overwrite the previous value of asd, and you never use it later in the loop.
