C#从逗号分隔的文本文件中读取到二维数组中 [英] C# Read from text file separated by commas into 2d array

问题描述

我目前有这个:

using (StreamReader sr = new StreamReader("answers.txt")){for (iCountLine = 0; iCountLine <10; iCountLine++){for (iCountAnswer = 0; iCountAnswer <4; iCountAnswer++){sQuestionAnswers[iCountLine, iCountAnswer] =}}}

我的文本文件格式如下(10 行文本，每行 4 个项目，用逗号分隔):

<块引用>

例子，例子，例子，例子123, 123, 123, 123

我不确定在 for 循环中的="之后需要什么才能读取文本文件的内容并将其拆分为二维数组.

解决方案

我不确定在 for 循环中的="之后需要什么

上面还缺少一行:

var tokens = sr.ReadLine().Split(',');

现在带有 = 的行看起来像这样:

sQuestionAnswers[iCountLine, iCountAnswer] = tokens[iCountAnswer];

I currently have this:

using (StreamReader sr = new StreamReader("answers.txt"))
{
    for (iCountLine = 0; iCountLine < 10; iCountLine++)
    {
         for (iCountAnswer = 0; iCountAnswer < 4; iCountAnswer++)
         {
             sQuestionAnswers[iCountLine, iCountAnswer] = 
         }
    }
}

My text file is formatted like this (10 lines of text, with 4 items on each line separated by commas):

example, example, example, example 
123, 123, 123, 123

I'm not sure what I need after the "=" in the for loop to get it to read and split the contents of the text file into the 2D array.

解决方案

I'm not sure what I need after the "=" in the for loop

There's also a line missing above it:

var tokens = sr.ReadLine().Split(',');

Now the line with = would look like this:

sQuestionAnswers[iCountLine, iCountAnswer] = tokens[iCountAnswer];
