I need to read a line in a file. Based on the first 3 characters in the file, I can determine a type of record.
This indicates the number of strings the line needs to be split into.
I need to hold all lines of the same type in a List.
How do I do this?
My sample file would look like
123|gf|hf|gr|9
145*gf*43*434*9*645*554
123|grf|fe|yr|9
So all 123 would be in a list of string array type of length 4 like :
public List<string[]> NTE =new List<string[4]>();
Except declaring a length isn't being accepted by the compiler
You could use
List<string[]> NTE =new List<string[]>();
And then as you need to add an element to the NTE
, you only need to specify that the size will be 4
:
NTE.Add(new string[4]); //here it is defined having size of 4, not in the list declaration
Then when you use it:
NTE[0] = ...something
That is going to be a string[4]
array
class ArrayofFour
{
string[] a = new string[4];
public string this[int i]
{
get
{
return a[i];
}
set
{
a[i] = value;
}
}
}
Use the ArrayofFour instead of an array, you can use it like an array using the indexers. This will take care of validation you need.
Then you can have a List<ArrayofFour> NTE = new List<ArrayofFour>();
I think this is what you need or at least help you get there.
