c# - What is a good way to rename multiple parameters that share the same purpose?

Question

What is the common way of naming parameters in a method like the following?

void MyMethod(int[] series1, int[] series2) { ... }

The two arrays there have the same purpose, maybe the method takes two arrays of names, or two series, or something similar. What is a common way to name such parameters? Would you use parameter1, parameter2, ... or firstParameter, secondParameter, ... or something else?

I would appreciate if you could give me an example of such a method in the .NET Framework itself.

Answer 1

这里有一些例子：

• Tuple.Create<T1, T2> 方法 (T1, T2)

  public static Tuple<T1, T2> Create<T1, T2>(T1 item1, T2 item2)
  

• String.Compare 方法（字符串，字符串）

  public static int Compare(string strA, string strB)
  

• 字符串等式运算符

  public static bool operator ==(string a, string b)
  

• Object.ReferenceEquals 方法

  public static bool ReferenceEquals(Object objA, Object objB)
  

• XNode.DeepEquals 方法

  public static bool DeepEquals(XNode n1, XNode n2)
  

• Expression.Equal 方法（表达式，表达式）

  public static BinaryExpression Equal(Expression left, Expression right)
  

• TimeSpan.Compare 方法

  public static int Compare(TimeSpan t1, TimeSpan t2)
  

• String.Concat 方法（字符串，字符串）

  public static string Concat(string str0, string str1)
  

我不认为有一个在整个 .NET 框架中始终如一地使用的约定。
方法名称清楚地说明了参数的含义。

Answer 2

The way you have done it is common.

However, if the method reflects a documented algorithm, then using names that match that algorithm is better.
