分解一串 [英] Breaking up a string

问题描述

大家好，

我正在从C#应用程序读取txt文件.读取
时 第一行(然后是下一行，等等).它被裁剪为"line"字符串.(line
按行)

在我的txt文件中，在该行中，我使用"*"分隔了值.
因此，我需要将其分解为单独的值.当它
看到*，它必须知道它是该值的结尾.

因此，逐行安装，我希望它逐个值.

请任何帮助将被应用！

这是我使用的代码:

Hi all,

I am reading a txt file from C# app. When it reads the
first line (and then the next etc..) it gets trown into the "line" string.(line
by line)

In my txt file, in the line I seperated the values using the "*"
So I need it to break up the line into seperate values. When it
sees a * it must know it is the end of that value.

So insted of line by line, I want it value by value.

Please any help would be appriciated!!

Here is the code I used:

int counter = 0;
            string line;

            // Read the file and display it line by line.
            System.IO.StreamReader file =
               new System.IO.StreamReader("C:/Users/user/Downloads/test1.txt");
            while ((line = file.ReadLine()) != null)
            {
                MessageBox.Show(line);
                counter++;
            }

            file.Close();

推荐答案

使用

Use the String.Split[^] method.

我创建了一个名为1.txt的文件，其值

I have created a file named 1.txt having value

asd*fasfda*fdaaaaa*aaaaaaaaa
dddddddd*ddd

现在，为了基于"*"分隔值，我使用了以下代码

Now for separating values based on "*" I have used following code

static void Main(string[] args)
{
    string text="";
    text = System.IO.File.ReadAllText(@"F:\Test\1.txt");
    string[] Values = text.Split(''*'');

    int counter = 0;
    while (counter < Values.Length)
    {
        Console.Write(Values[counter++]);
        Console.Write("\n");
    }

}

请勿使用ReadLine()

以字符串值读取整个文件.然后用*
分开

Do not use ReadLine()

Read the whole file as a string value. Then separate it by *

System.IO.StreamReader file =
     new System.IO.StreamReader("C:/Users/user/Downloads/test1.txt");


string wholeFile = file.ReadToEnd();

string[] separatedFile = wholeFile.Split('*');
