CS0623:Array initializers can only be used in a variable or field initializer. Try using a new expression instead. CS0650:Bad array declarator: To declare a managed array the rank specifier precedes the variable's identifier. To declare a fixed size buffer field, use the fixed keyword before...
When you create an anonymous type that contains an array, the array must be implicitly typed in the type's object initializer. In the following example,contactsis an implicitly typed array of anonymous types, each of which contains an array namedPhoneNumbers. Thevarkeyword isn't used inside th...
