问题 I want to set private fields using LINQ expressions. I have this code: //parameter "target", the object on which to set the field `field` ParameterExpression targetExp = Expression.Parameter(typeof(object), "target"); //parameter "value" the value to be set in the `field` on "target" ParameterExpression valueExp = Expression.Parameter(typeof(object), "value"); //cast the target from object to its correct type Expression castTartgetExp = Expression.Convert(targetExp, type); //cast the value to

问题 I have the following code which creates a dynamic object that is assigned to the smtpClient variable. public class TranferManager { public void Tranfer(Account from, Account to, Money amount) { // Perform the required actions var smtpClient = New.SmtpClient(); smtpClient.Send("info@bank.com", "from.Email", "Tranfer", "?"); // In the previous line I get a Microsoft.CSharp.RuntimeBinder.RuntimeBinderException // with the description = "'object' does not contain a definition for 'Send'" } }

问题 I'm trying to use reflection to grab all public methods that are declared explicitly in the class (so c.getMethods() won't work since it grabs superclass methods too). I can use Method[] allMethods = c.getDeclaredMethods(); to grab methods from just that class, but I only want to use public ones. At this point, I'm trying to grab modifiers and do certain actions based on this, but for some reason the modifier value shown in the debugger and the modifier value output isn't the same. For

问题 .net 3.5, VS 2010... this is for an asp.net website. I have an class called Agency. there is a second class called Agency_Queries. Agency_Queries inhertis the Agency class. I'm trying to create a function that will copy the like properties in Agency to Agency_Queries. I figured out how to do that.. but when i try to make it more generic so that i can pass in my class name and lists i'm doing something wrong. So if there is an list(of Agency) that needs to be copied to list(of Agency_Queries)

问题 I am working with a reflection based object translator. it basically loops through properties of an object, and assigns the values to properties with the same name/type on the translated object. ObjectA.Name = "Joe" translates to: ObjectB.Name = "Joe" I need to put a special case, for when a property is a custom class such as: ObjectA.Address i was hoping i could detect such properties with IsClass flag of PropertyType propInfo.PropertyType.IsClass but this flag also appears to return true

问题 I am curious if someone can describe how to enumerate ADSI methods available via a bound instance as [ADSI]$instance.psbase.Invoke() ? Research has turned up "refer to the docs for the ADSI interface". but I am not particularly happy with that answer. If I instantiate with: [ADSI]$lhost_group="WinNT://./Administrators,group" Then attempt: @($lhost_group.psbase.Invoke("Members")) | foreach-object {$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null)} Powershell will return the

问题 Hi i am using reflections to achieve something. I have been given class name, method name of that class and parameter values that needs to be passed to that method in a file(Take any file. Not a constraint). I have to call that method with the parameters. This methods do not return anything. There is a huge list of methods in this classes and parameter list of each varies. E.g: method1(String, String, int, boolean) method1(String, int, boolean) and likewise i have different permutations and

问题 Is there any way to get value of private static field from known class using reflection? 回答1: Yes. Type type = typeof(TheClass); FieldInfo info = type.GetField(name, BindingFlags.NonPublic | BindingFlags.Static); object value = info.GetValue(null); This is for a field. For a property, change type.GetField to type.GetProperty . You can also access private methods in a similar fashion. 回答2: I suppose someone should ask whether this is a good idea or not? It creates a dependency on the private
