如何使 args 类型的变量将引号或字符串作为参数？

当我通过 CMD 运行代码时，消息会发送到：

void Main(string[]args)

正如每个人在 Visual Studio 上使用 C# 时所做的那样。但是当您从 CMD 运行代码并输入消息时。看来参数可以接受如下消息：

When I run my code through the CMD, the message gets sent into:

void Main(string[]args)

As everybody does if they use C# on visual studio. But when you run your code from CMD and type a message. it appears the argument can take in a message such as:

您可以将带引号的文本视为一个字符串，而不使用 Split 函数，而是使用正则表达式。
以以下代码片段为例：

// In your case just read from the textBox for input
string input = "cars \"testing string\"";

// This code will split the input string along spaces,
// while keeping quoted strings together
string[] tmp = Regex.Split(input, 
    "(?<=^[^\"]*(?:\"[^\"]*\"[^\"]*)*) (?=(?:[^\"]*\"[^\"]*\")*[^\"]*$)");

// Now must remove the quotes from the Regex'd string
string[] args = tmp.Select(str => str.Replace("\"", "")).ToArray();

// Now when printing the arguments, they are correctly split
for (int i = 0; i < args.Length; i++)
{
    Console.WriteLine("args[" + i + "]:'" + args[i] + "'");
}

我在此链接（位于堆栈溢出）中找到了您需要的特定正则表达式字符串。

You can treat quoted text as one string without using the Split function, instead making use of Regex.
Take the following snippet as an example:

// In your case just read from the textBox for input
string input = "cars \"testing string\"";

// This code will split the input string along spaces,
// while keeping quoted strings together
string[] tmp = Regex.Split(input, 
    "(?<=^[^\"]*(?:\"[^\"]*\"[^\"]*)*) (?=(?:[^\"]*\"[^\"]*\")*[^\"]*$)");

// Now must remove the quotes from the Regex'd string
string[] args = tmp.Select(str => str.Replace("\"", "")).ToArray();

// Now when printing the arguments, they are correctly split
for (int i = 0; i < args.Length; i++)
{
    Console.WriteLine("args[" + i + "]:'" + args[i] + "'");
}

I found the particular regex string you needed at this link, here on stack overflow.
