如何将字典的内容写入文本文件？ [英] How to write the content of a dictionary to a text file?

问题描述

我有一个类型为Dictionary的字典对象

，并尝试使用StreamWriter将整个内容输出到文本文件，但无法从字典中找到正确的方法使用（StreamWriter sw = new StreamWriter（myfile.txt））
$ {


$ sw.WriteLine（dictionary.First（））;

}

我只能检索第一个元素，它被一个方括号加上一个逗号分隔符之间：

[Peter，Admin]

很高兴有[Peter Admin]（没有逗号）

解决方案

您需要自行循环输入：

  using（StreamWriter file = new StreamWriter（myfile.txt））
 foreach（字典中的var项）
 file.WriteLine（[{0} {1}]，entry.Key，entry.Value）; 
  

I have a dictionary object of type Dictionary

and trying to use StreamWriter to output the entire content to a text file but failed to find the correct method from the Dictionary class.

using (StreamWriter sw = new StreamWriter("myfile.txt"))
        {
            sw.WriteLine(dictionary.First());

        }

I can only retrieve the first element and it is bounded by a square bracket plus a comma separator in between as well:

[Peter, Admin]

and would be nice to have [Peter Admin] (without the comma)

解决方案

You need to loop over the entries yourself:

using (StreamWriter file = new StreamWriter("myfile.txt"))
    foreach (var entry in dictionary)
        file.WriteLine("[{0} {1}]", entry.Key, entry.Value);
