在C＃中接受n个参数的方法

Question

I am Developing an windows Application, oftentimes I need to clear the Textboxes whenever the user save the Record or click on clear button. Currently i am using this code txtboxname.text=string.empty; for each textbox

So can it be possible to write a method that accept the n number of parameter like reading the all the Textboxes in an array and using foreach we can clear them

the main requirement is to write a method which accept the n number of parameter ie The parameter size will be unknown.

If any body having idea about how to do this then please help me. Thanks in Advance.

Answer 1

With the params keyword.

Here is an example:

public void MyMethod(params int[] numbers)
{
   for (int i = 0; i < numbers.Length; i++)
   {
       //numbers[i] is one of the parameters
   }
}

Answer 2

Have a look at params

The params keyword lets you specify a method parameter that takes a variable number of arguments.

Answer 3

您可以使用params ，例如Foo(params Bar[] bars)将接受任意数量的Bar实例作为输入。

Answer 4

You could also pass a collection eg a dictionary or List to your method as a parameter.

Eg

public void DoSomething(List<myCustomObject> lst){
    ...
}

Answer 5

是的，您可以将一个TextBoxes TextBox[]数组作为方法的paremter，然后您可以在方法中迭代它们。
