C# parsing a text file and storing the values in an array

Question

I am trying to read in a text file which has this format below, into an array:

Previous errors were for Test id \'1234567\' Error id \'12345678\'
Previous errors         


        

Answer 1

A very basic solution is read the lines, split them and find valid integers:

List test = new List();
List error = new List();

using (var reader = new StreamReader(@"D:\Temp\AccessEmail.txt")){
     string line;
     while ((line = reader.ReadLine()) != null){   
        //split the line
        string[] parts = line.Split(new[]{"Error"}, StringSplitOptions.None);

        //get valid integers
        test.Add(GetInt(parts[0].Split(' ', '\'')));
        error.Add(GetInt(parts[1].Split(' ', '\'')));
     }
}

//print the number of elements in the lists
Console.WriteLine(test.Count); 
Console.WriteLine(error.Count);

int GetInt(string[] a){
    int i = 0;

    foreach (string s in a)
       int.TryParse(s, out i);

    return i;
}
