如何使用VS2005输出所有环境变量

Posted 2023-02-19

IDictionary environment = Environment.GetEnvironmentVariables();

// 打印表头
Console.WriteLine("环境变量名\t=\t环境变量值");

// 遍历environment中所有键值
foreach (string environmentKey in environment.Keys)

// 打印出所有环境变量的名称和值
Console.WriteLine("0\t=\t1", environmentKey, environment[environmentKey].ToString());

为什么利用以上的代码无法实现将环境变量显示出来，如果以上代码 有什么问题的话，请更正一下，如果你有什么更好的方法的话，就将你的代码留下，只要能将环境变量打印出来，不过最好还是能在我的代码之上改一下。
呵呵 分数不是很多

参考技术A var e = System.Environment.GetEnvironmentVariables();
foreach (var k in e.Keys)

var v = e[k];
Console.WriteLine("0 = 1", k, v);

这样行么？

其中的？？？是我修改的，为了安全原因。 参考技术B //获取所有的系统环境变量名称和值
Console.WriteLine("名称\t\t=\t\t值");
foreach (DictionaryEntry de in Environment.GetEnvironmentVariables(EnvironmentVariableTarget.Machine))

Console.WriteLine("0=1", de.Key, de.Value);


//取得用户环境变量的键值
Console.WriteLine("键\t\t=\t\t值");
Console.WriteLine(System.Environment.GetEnvironmentVariable("Path", System.EnvironmentVariableTarget.User));本回答被提问者采纳 参考技术C //获取所有的系统环境变量名称和值
Console.WriteLine("名称\t\t=\t\t值");
foreach (DictionaryEntry de in Environment.GetEnvironmentVariables(EnvironmentVariableTarget.Machine))

Console.WriteLine("0=1", de.Key, de.Value);


//取得用户环境变量的键值
Console.WriteLine("键\t\t=\t\t值");
