Extracting an int among a line of text and splitting

I am attempting to split a line from a text file into 4 strings and 1 int. I do not know how to extract the int part.

Can someone help me out here?

StreamReader infil = new StreamReader("moviefile.txt", Encoding.GetEncoding(28591));
for (;;)
{
    string line = infil.ReadLine();
    if (line == null) break;

    string[] parts = line.Split('\t');

    Movie movie = new Movie();
    movie.title = parts[0];
    movie.genre = parts[1];
    movie.release = parts[2];
    movie.actor = parts[3];
    movie.director = parts[4];

    AddMovie(movie);
}

Say the string is "SomeTitle SomeGenre SomeRelease SomeActor SomeDirectore 2008" using your code:

string[] parts = line.Split('\t');

Movie movie = new Movie();
movie.title = parts[0];
movie.genre = parts[1];
movie.release = parts[2];
movie.actor = parts[3];
movie.director = parts[4];
movie.year = int.Parse(parts[5]);

That should work just fine.

You can simply parse a string to int

Assuming 'release' was supposed to be parsed into integer,

movie.release = int.parse(parts[2]);

I think what you'll find slightly confusing is that in C#, there is Convert.ToInt32, Int32.Parse, and Int32.TryParse (and thats just for Int32... there are more variations for all the other ints and types)

StreamReader infil = new StreamReader("moviefile.txt", Encoding.GetEncoding(28591));
for (;;)
{
    [...]
    movie.release = Int32.Parse(parts[2]);  // Parse parts[2] into an 32-bit (4-byte) integer.
    [...]    
    AddMovie(movie);
}

Assuming 'release' is the year the movie was released, as an integer:

int release;
bool didParse;
while (true)
{
    string line = infil.ReadLine();
    if (line == null) break;

    string[] parts = line.Split('\t');

    Movie movie = new Movie();
    movie.title = parts[0];
    movie.genre = parts[1];
    didParse = Int.TryParse(parts[2], out release);
    movie.release = (didParse) ? release: -1;
    movie.actor = parts[3];
    movie.director = parts[4];

    AddMovie(movie);
}

You didn't specify which member of Movie was an int.

It's fairly straightforward. For example, if genre was your int:

 movie.genre = Convert.ToInt32(parts[1]);
