问题 Is there a way to refer to a property name with a variable? Scenario: Object A have public integer property X an Z, so... public void setProperty(int index, int value) { string property = ""; if (index == 1) { // set the property X with 'value' property = "X"; } else { // set the property Z with 'value' property = "Z"; } A.{property} = value; } This is a silly example so please believe, I have an use for this. 回答1: Easy: a.GetType().GetProperty("X").SetValue(a, value); Note that GetProperty(

问题 I want to get all of the types from my assembly, but I don't have the references, nor do I care about them. What does finding the interface types have to do with the references? and is there a way for me to get around this? Assembly assembly = Assembly.LoadFrom(myAssemblyPath); Type[] typeArray = assembly.GetTypes(); Throws: FileNotFoundException Could not load file or assembly 'Some referenced assembly' or one of its dependencies. The system cannot find the file specified. 回答1: Loading an

问题 I'm trying to use System.Reflections to get a DbSet<T> dynamically from its name. What I've got right now is: The DbSet name The DbSet 's Type stored on a variable The issue I'm facing comes out when trying to use the dbcontext.Set<T>() method, since (these are my tries so far): When I try to assign to <T> my DbSet Type , it throws me the following compilation error: "XXX is a variable but is used like a type" If I try with using both the Extension methods that you will find below in my code
