Convert Static to Extension Method refactoring
This refactoring helps you convert a static method to an extension method, provided that the static method:
Has at least one parameter.
Resides in a non-generic, non-nested static class.
Consider the following example:
Before refactoring | After refactoring |
|---|---|
|
static class Foo
{
public static string Reverse(string input)
{
var chars = input.ToCharArray();
Array.Reverse(chars);
return new string(chars);
}
static void Test(string str)
{
str = Reverse(str);
}
}
|
static class Foo
{
public static string Reverse(this string input)
{
var chars = input.ToCharArray();
Array.Reverse(chars);
return new string(chars);
}
static void Test(string str)
{
str = str.Reverse();
}
}
