# Indeterminate parameters
|
|
|
|
Let's imagine we need to write a method where the number of parameters are variable. How can we do that? Well, C# (and other languages) has an easy way to do so; by using the `params` keyword on a method's parameter we can call that method with a variable number of parameters.
|
|
|
|
## Example
|
|
```
|
|
public static void Main (string[] args) {
|
|
// Call PrintParams with 3 parameters
|
|
PrintParams(1, 2, 3);
|
|
|
|
// Call PrintParams with 1 parameter
|
|
PrintParams(4);
|
|
}
|
|
|
|
public static void PrintParams(params int[] values)
|
|
{
|
|
// Iterate through parameters
|
|
for (int i = 0; i < values.Length; i++)
|
|
{
|
|
Console.WriteLine("Parameter {0} is {1}", i, values[i]);
|
|
}
|
|
}
|
|
```
|
|
|
|
## Output:
|
|
```
|
|
> Parameter 0 is 1
|
|
> Parameter 1 is 2
|
|
> Parameter 2 is 3
|
|
> Parameter 0 is 4
|
|
```
