Method Parameter Validation Attribute

Question

Powershell offers a ValidateScript parameter attribute to check given attributes. Example:

function foo{
    Param(
       [ValidateScript({Test-Path $_ -PathType Leaf})] 
       [string]
       $FilePath,
    ....

Is there an equivalent available in C#, to validate parameters of a method? So that I can define a method in c# like:

...
public static string Foo (
   [Validate(p => p <1)]
   int p) {
   ...
}

Please share some more light on what this param does for PS. — Nikhil Agrawal

Yes, of cause. Here is a link. Powershell is built on .NET Framework, so it can access all classes of standart library. Also, check this answer, maybe it can help you. — Backs

@Igor: I`ve update my question. I'm interested at parameter checking "just in general". — Moerwald
