c# - 在一行文本中提取一个整数并拆分

Question

我试图将文本文件中的一行拆分为 4 个字符串和 1 个整数。我不知道如何提取 int 部分。

有人可以帮我吗？

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);
}

Answer 1

假设 'release' 是电影发行的年份，作为整数:

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);
}
