嗨，我想做一个原子模拟游戏，我可以从文本文件中读取我的数据，并使用模拟/游戏的数据。我读了文件，但我有困难找到从字符串数组的组合。txt文件看起来像这样:1,H，氢，1,1+3、李锂、7、1 + 

static void Main(string[] args)
{
    string commapostition;
    string[] list = new string[44];
    StreamReader rFile = new StreamReader(@"JUNK1.txt");
    for (int i = 0; i < 44; i++)
    {
        list[i] = rFile.ReadLine();
    }
    rFile.Close();
    for (int i = 0; i < 44; i++)
    {
        commapostition = list[i].IndexOf(',');
    }
}

如何从数组中读取逗号位置

如果你的文件的每一行看起来都像你发布的:

1,H,Hydrogen,1,1+

而Atomic #, Symbol, Name, Mass, Charge的阶是常数，你可以这样做:

static void Main(string[] args)
{
    string filename = @"JUNK1.txt";
    string[] lines = File.ReadAllLines(fileName);
    for (int i = 0; i < lines.Length; i++)
    {
        string[] entries = lines[i].Split(',');
        string atomicNumber = entries[0];
        string symbol = entries[1];
        string name = entries[2];
        string mass = entries[3];
        string charge = entries[4];
        // Do stuff with these values...
    }
}

假设您有一个文本文件JUNK1.txt，其行为:

1,H,Hydrogen,1,1+
3,Li,Lithium,7,1+

你可以这样读这行:

static void Main(string[] args)
{
    // Path to the file you want to read in
    var filePath = "path/to/JUNK1.txt";
    // This will give you back an array of strings for each line of the file
    var fileLines = File.ReadAllLines(filePath);
    // Loop through each line in the file
    foreach (var line in fileLines)
    {
        // This will give you an array of all the values that were separated by a comma
        var valuesSeparatedByCommas = line.Split(',');
        // Do whatever with the array valuesSeparatedByCommas
    }
}

在第一行执行上述代码后，变量valuesSeparatedByCommas数组看起来如下所示:

  0   1      2       3    4
+---+---+----------+---+----+
| 1 | H | Hydrogen | 1 | 1+ | 
+---+---+----------+---+-----

现在你可以根据它的索引访问该行的每一部分:

// valueAtPosition0 will be '1'
var valueAtPosition0 = valuesSeparatedByCommas[0];
// valueAtPosition1 will be 'H'
var valueAtPosition1 = valuesSeparatedByCommas[1];
