You can use File.ReadAllLines method to load the file into an array. You can then use a for loop to loop through the lines, and the string type's Split method to separate each line into another array, and store the values in your formatted array.
您可以使用 File.ReadAllLines 方法将文件加载到数组中。然后，您可以使用 for 循环遍历行，并使用字符串类型的 Split 方法将每一行分隔到另一个数组中，并将值存储在格式化的数组中。
Something like:
就像是：
static void Main(string[] args)
{
var lines = File.ReadAllLines("filename.txt");
for (int i = 0; i < lines.Length; i++)
{
var fields = lines[i].Split(' ');
}
}

Do not reinvent the wheel. Can use for example fast csv readerwhere you can specify a delimeteryou need.
不要重新发明轮子。可以使用例如快速 csv 阅读器，您可以在其中指定delimeter您需要的。
There are plenty others on internet like that, just search and pick that one which fits your needs.
互联网上还有很多其他类似的东西，只需搜索并选择适合您需求的那个。

This answer assumes you don't know how much whitespace is between each string in a given line.
这个答案假设您不知道给定行中每个字符串之间有多少空格。
// Method to split a line into a string array separated by whitespace
private string[] Splitter(string input)
{
return Regex.Split(intput, @"\W+");
}
// Another code snippet to read the file and break the lines into arrays
// of strings and store the arrays in a list.
List<String[]> arrayList = new List<String[]>();
using (FileStream fStream = File.OpenRead(@"C:\SomeDirectory\SomeFile.txt"))
{
using(TextReader reader = new StreamReader(fStream))
{
string line = "";
while(!String.IsNullOrEmpty(line = reader.ReadLine()))
{
arrayList.Add(Splitter(line));
}
}
}
