ColumnNames is a property of type List<String> so when you are setting up you need to pass a List<String> in the Returns call as an argument (or a func which return a List<String>) But with this line you are trying to return just a string input.SetupGet(x => x.ColumnNames).Returns(temp[0]); which is causing the exception. Change it … Read more
Use a lambda expression MyClass result = list.Find(x => x.GetId() == “xy”); Note: C# has a built-in syntax for properties. Instead of writing getter and setter as ordinary methods (as you might be used to from Java), write private string _id; public string Id { get { return _id; } set { _id = value; … Read more
Fields and properties look the same, but they are not. Properties are methods and as such there are certain things that are not supported for properties, and some things that may happen with properties but never in the case of fields. Here’s a list of differences: Fields can be used as input to out/ref arguments. … Read more
Look at the comments. You will see that for CSS properties, the key notation is not compatible with a number of properties. Using the camel case key notation therefore is the current way: obj.style-attr // would become obj[“styleAttr”] Use key notation rather than dot style[“text-align”] All arrays in JavaScript are objects and all objects are … Read more
Yes, it is: /// <summary> /// Returns a _private_ Property Value from a given Object. Uses Reflection. /// Throws a ArgumentOutOfRangeException if the Property is not found. /// </summary> /// <typeparam name=”T”>Type of the Property</typeparam> /// <param name=”obj”>Object from where the Property Value is returned</param> /// <param name=”propName”>Propertyname as string.</param> /// <returns>PropertyValue</returns> public static T … Read more
There are two ways to access properties of an object: Dot notation: something.bar Bracket notation: something[‘bar’] The value between the brackets can be any expression. Therefore, if the property name is stored in a variable, you have to use bracket notation: var something = { bar: ‘foo’ }; var foo = ‘bar’; // both x … Read more
Why am I not allowed to just give it another value? You are definitely allowed to give an inherited property a different value. You can do it if you initialize the property in a constructor that takes that initial value, and pass a different value from the derived class: class Jedi { // I made … Read more
How about PropertiesLoaderUtils? Resource resource = new ClassPathResource(“/my.properties”); Properties props = PropertiesLoaderUtils.loadProperties(resource);
Other examples would be validation/filtering of the set attributes (forcing them to be in bounds or acceptable) and lazy evaluation of complex or rapidly changing terms. Complex calculation hidden behind an attribute: class PDB_Calculator(object): … @property def protein_folding_angle(self): # number crunching, remote server calls, etc # all results in an angle set in ‘some_angle’ # … Read more
Take a look at the Apple Docs. Basically, if you say nonatomic, and you generate the accessors using @synthesize, then if multiple threads try to change/read the property at once, badness can happen. You can get partially-written values or over-released/retained objects, which can easily lead to crashes. (This is potentially a lot faster than an … Read more
