Well, neither keyword is present in the language, so the question is somewhat vague. The best that can be done is to look how each term is used in C# language specification (1.6.6.1 "Parameters"):
嗯，这两个关键字都没有出现在语言中，所以这个问题有点含糊。最好的办法是查看每个术语在 C# 语言规范（1.6.6.1“参数”）中的使用方式：
Parametersare used to pass values or variable references to methods. The parameters of a method get their actual values from the argumentsthat are specified when the method is invoked.
参数用于将值或变量引用传递给方法。方法的参数从调用方法时指定的参数中获取其实际值。
So, "parameters" refer to names, and "arguments" refer to valuesbound to those names. E.g.:
因此，“参数”指的是名称，而“参数”指的是绑定到这些名称的值。例如：
void Foo(int x, int y); // x and y are parameters
Foo(1, 2); // 1 and 2 are arguments

In the context of functions yes, they are the same, sometimes if you are talking about passing data to executables such as MyApp.exe /a:value /b:somethingelse, this might be refered to as arguments
在函数的上下文中，是的，它们是相同的，有时如果您正在谈论将数据传递给诸如 MyApp.exe /a:value /b:somethingelse 之类的可执行文件，这可能被称为参数

Typically, I refer to command-line arguments, as arguments. Arguments to a method or function I typically call parameters.
通常，我将命令行参数称为参数。方法或函数的参数我通常调用参数。
However, this isn't convention and both can be used interchangeably without people getting confused.
但是，这不是约定俗成的，两者可以互换使用，而不会让人感到困惑。
