angular material autocomplete prevents reactive from setValue from working

问题 Edit: Resolved with Jojofoulk's comment. when using the autocomplete components of angular-material, I'm trying to use setValue to the input form, but its [matAutocomplete] attribute is preventing setValue from showing on the input. Inspecting the reactive control reveals the value is right, and removing [matAutocomplete] makes it work, but with it it's just not showing up. <mat-list-item role="listitem" *ngFor="let skill of curObj.skills;index as ind"> <div> <mat-form-field> <input type=

一：setObject:ForKey:与setValue:ForKey:存值区别与联系 1.setObject:ForKey: 是NSMutableDictionary特有的；setValue:ForKey:是KVC的主要方法； 2.setObject:ForKey:中object对象不能为nil,不然会报错；key的参数只要是对象就可以，并局限于NSString；setValue:ForKey:中Value值可以为nil，此时会自动调用removeObject:forKey:方法；key的参数只能是NSString类型； 3.nil与null是不同的,[NSNull null]表示是一个空的对象,并不是nil； 4.setValue:ForKey:是在NSObject对象中创建的,即所有的对象都有这个方法，可以用于任何类(方法调用者是对象的时候); 二：objectForKey:和valueForKey:取值区别与联系 NSDictioary取值的时候有两个方法,objectForKey:和valueForKey:(建议用objectForKey:) 1.若key值不是以@符合开头, 两者是相同的； 2.若key值是以@开头, 例如：@“@zhangcyKey”,则valueForKey:会去掉@,然后用剩下的部分执行[super valueForKey]; 3.例子：

问题 Been using a Copy method with this code in it in various places in previous projects (to deal with objects that have same named properties but do not derive from a common base class or implement a common interface). New place of work, new codebase - now it's failing at the SetValue with "Object does not match target type" even on very simple examples... and it worked last week.... public static void Copy(object fromObj, object toObj) { Type fromObjectType = fromObj.GetType(); Type
