Question

我在Selenium Web驱动程序中编写测试用例，我想将结果输出到日志文件中。测试用例应在文本文件中按行编号。编号已经实现，但附加测试用例是我无法实现的。问题是for循环，我想追加引用传递的变量组合。这些变量将是测试用例。如果需要更多解释，请告诉我。

问题是连接定义的变量只会为所有变量附加一个值。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;

namespace ConsoleApplication5
{
    class Class1
    {
        public static int counter;
        public static String[] test = {"1", "2" };
        public static String[] test1 = { "a", "b" };

        public static void Main(String[] args)
        {
            new Class1().testing2();
        }

        public String testing(String ab, String cd)
        {
            //Count the number of times the method is called
            ++counter;
            //Write it to a text file
            File.WriteAllText(@"C:\Users\ken4ward\Desktop\Tidy\WriteLines.txt", counter.ToString());
            //Read from that text file
            String Readfiles = File.ReadAllText(@"C:\Users\ken4ward\Desktop\Tidy\WriteLines.txt");
            //Convert to integer
            Int32 myInt = Int32.Parse(Readfiles);
            //Store in array variable
            String[] start = new String[myInt];
            //iterate through
            for (int i = 0; i < myInt; ++i)
            {
                **start[i] = (i + 1).ToString() +ab +cd;**
            }
            //Write into another text file on new lines
            File.WriteAllLines(@"C:\Users\ken4ward\Desktop\Tidy\Writing.txt", start);

            String gb = ab; String th = cd; String you = ab + cd;
            return you;   
        }

        public void testing2()
        { 
            foreach(var item in Class1.test)
            {
                foreach (var item1 in Class1.test1)
                {
                    String test = testing(item, item1);
                    Console.WriteLine(test);
                    Console.ReadLine();
                }
            }
        }
    }
}

当我运行它时，这是文本文件中的输出：

1 2b
2 2b
3 2b
4 2b

我想在文本文件中输出的内容是：

1 1a
2 1b
3 2a
4 2b

添加全局变量

public static String[] lines = { };

将testing()更改为：

    public String testing(String ab, String cd)
    {
        //Count the number of times the method is called
        ++counter;
        //Write it to a text file
        File.WriteAllText(@"C:\Users\ken4ward\Desktop\Tidy\WriteLines.txt", counter.ToString());
        //Read from that text file
        String Readfiles = File.ReadAllText(@"C:\Users\ken4ward\Desktop\Tidy\WriteLines.txt");
        //Convert to integer
        Int32 myInt = Int32.Parse(Readfiles);
        //Store in array variable
        String start = myInt.ToString() + ab + cd;
        //Store the new data in the array
        Array.Resize(ref lines, lines.Length + 1);
        lines[lines.GetUpperBound(0)] = start;
        //Write into another text file on new lines
        File.WriteAllLines(@"C:\Users\ken4ward\Desktop\Tidy\Writing.txt", lines);
        //String gb = ab; String th = cd;
        String you = ab + cd;

        return you;   
    }

由于WriteAllText表示要覆盖该文件。

for (int i = 0; i < myInt; ++i)
{
    start[i] = (i + 1).ToString() +ab +cd;
}

上面的代码(ab + cd)等于2b，这意味着您只更改了行号，并且2b保持不变。

将“由引用变量调用”附加到文本文件中
