YAGuard 1.0.1

YAGuard

Yet Another Guard argument validation package. There's no need to provide the name of the argument being checked. Usage: public void MyFunc(string myArg) { Guard.AgainstNull(myArg); } In case myArg is null, this will throw an ArgumentNullException with the correct argument name.

Supports single line argument checking and assignment as well: string result = Assign.NotNull(string source); will set result to source in case it is not null, or throw an appropriate ArgumentNullException in case it is null.

##Examples To validate method arguments: public void MyMethod(string myArg) { Guard.AgainstNull(myArg); // Will throw ArgumentNullException when myArg is null. Guard.AgainstNullOrEmptyString(myArg); // Will throw ArgumentException when myArg is null or empty. Guard.AgainstLongString(myArg, 10); // Will throw ArgumentException when myArg is longer then 10 characters.

MyProperty = myArg;
...

}

Use intellisense for a full list of supported validation methods.

To use a single line of code to validate and assign values to variables: public void MyMethod(string myArg) { MyProperty = Assign.NotNull(myArg); // Will throw ArgumentNullException when myArg is null, or assign myArg to MyProperty if not null. ... }

#Release History ##v1.0.x Added support for the style Guard.Against...(myArg); which automatically resolves the name of the argument.

Removed support for the style Guard.Against...(myArg, new { myArg });

##v0.0.x Implemented two styles: Guard.Against...(myArg, argName); Guard.Against...(myArg, new { myArg }); the second one to help avoid typing the name of the argument. But it didn't really help when compared to nameof(myArg).
