Unity构造函数参数

class Entity:IEntityName { #region IEntityName Members public string FirstName { get; set; } public string LastName { get; set; } #endregion } public class Person:IPerson { public IEntityName EntityName; public Person() { } public Person(IEntityName EntityName) { this.EntityName = EntityName; } public string ReverseName() { return string.Format("Your reverse name is {0} {1}",EntityName.LastName, EntityName.FirstName); } public override string ToString() { return string.Format("Name is {0} {1}", EntityName.FirstName, EntityName.LastName); } } // Main Method private static string DisplayReverseName(string fName,string lName) { IUnityContainer container = new UnityContainer(); container.RegisterType().RegisterType(); IEntityName entityName = container.Resolve(); entityName.FirstName = fName; entityName.LastName = lName; var p = container.Resolve(); return p.ReverseName(); // firstName and lastName are still null } 

如何将firstName和lastName注入Person构造函数？

Answer 1

您可以使用ParameterOverride，如：

 var p = container.Resolve(new ParameterOverride("EntityName", entityName)); 

这告诉unity使用名为“EntityName”的参数将entityName实例提供给构造函数。
