Default for reference types is null => you have an array of nulls. You need to initialize each member of the array separatedly. houses[0] = new GameObject(..); Only then can you access the object without compilation errors. So you can explicitly initalize the array: for (int i = 0; i < houses.Length; i++) { houses[i] = new GameObject(); }

2013年1月13日 · // First object: Object objFirst = objects[0]; // Second object: Object objSecond = objects[1]; Or using Linq First(), Last() and so on... of course, to use those functions ( here a complete list) you have to add System.Linq to your using directives on the top of your source file and make sure you are referencing System.Core library in your ...

However, you can replace the array with a new one which contains the extra element. But it is easier and gives better performance to use an List<T> (uses interface IList ) for this. List<T> does not resize the array every time you add an item - instead it doubles it when needed.

2011年5月23日 · You need to fill the array with object instances. Create a constructor that takes parameters, then write new MyObject[] { new MyObject(a, b, c), new MyObject(d, e, f) }

Using the Watch window I can see my object is an array of some type as it tells me the number of elements and I can explode the tree view to see the elements themselves. Firstly, I need to check that the object passed is some kind of array (might be List, might be object[], etc). Then I need to iterate through that array.

Do you actually need to know the type of the array? Or do you only need the elements to be of a certain type? If the latter, you can simply filter only the elements that match what you want: string[] strings = array.OfType<string>();

2016年2月13日 · As the exception says, you can't convert cast a SomeEnumType[] to object[] - the former is an array where each value is a SomeEnumType value; the latter is an array where each element is a reference. With LINQ you can create a new array easily enough:

2012年3月28日 · Convert an object to a single item array of object (C#) 2. Converting an array to object. 0.

There is no way to allocate an array and invoke your class constructors on the items without constructing each item. You could shorten it (a tiny bit) from a loop using: clsPerson[] objArr = Enumerable.Range(0, 1000).Select(i => new clsPerson()).ToArray();

2011年8月18日 · I have an object which contains an array of any type (not a priory known type. So I cannot a simple cast in the code because I can determine the type just in the run-time!). How can I extract the content of array? For example: int[] …
