dynamic

问题 I have a helper class that uses a TypeBuilder to construct a dynamic type. It is used as follows : var tbh = new TypeBuilderHelper("MyType"); tbh.AddProperty<float>("Number", 0.0f); tbh.AddProperty<string>("String", "defaultStringValue"); tbh.Close(); var i1 = tbh.CreateInstance(); var i2 = tbh.CreateInstance(); I now want to add support for property attributes (existing attribute types, not dynamically generated types), along the lines of : public class TypeBuilderHelper { public void

问题 When trying to use a service in dynamically created component We got this error at run time ERROR Error: Can't resolve all parameters for class_1: (?). at syntaxError (compiler.js:485) at CompileMetadataResolver._getDependenciesMetadata (compiler.js:15664) at CompileMetadataResolver._getTypeMetadata (compiler.js:15499) at CompileMetadataResolver.getNonNormalizedDirectiveMetadata (compiler.js:15007) at CompileMetadataResolver.loadDirectiveMetadata (compiler.js:14862) at eval (compiler.js:34233

问题 I'm using a 3rd party web service where all it's methods have the following signature: SomeResponseClass SomeMethod(SomeRequestClass request) Every method has it's own request class and it's own response class, However there are a few things that all requests have in common, and all responses have in common. Every request class has a couple of properties for identification: username and token , and every response class have a couple of properties to indicate if there was an error: status and

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . If you search google for word segmentation there really are no very good descriptions of it and I'm just trying to fully understand the process a dynamic programming algorithm takes to find a segmentation of a string into individual words. Does anyone know a place where there is a good description of a word

问题 I have a few functions which I load in the ready() event. These basically make a list draggable, and other areas droppable/sortable. Eg. You can drag a clone into multiple areas (lists in divs), and within these multiple areas, you can sort/reorder them (but only within each area). This works perfectly. I have a button which dynamically creates a new area for items to be dropped into, then sorted. It creates the new area perfectly, but you cannot drop items into it, or then even make them

问题 Today I got this error from some old dynamic casting code (I have changed the last line and left out the rest of the stack trace): Item has already been added. Key in dictionary: 'Int32 Count[Object](System.Collections.Generic.IEnumerable`1[System.Object])' Key being added: 'Int32 Count[Object](System.Collections.Generic.IEnumerable`1[System.Object])' ---> System.ArgumentException: Item has already been added. Key in dictionary: 'Int32 Count[Object](System.Collections.Generic.IEnumerable`1

问题 I am trying to unpivot a table with multiple rows and columns. Each row needs to be extratced to 2 rows with specific columns and the column names need to be renamed and a new column needs to added based on the columns selected! I am including before and after sample data and a script to setup the data. CREATE TABLE #tmpProducts ( ProductId INT, ProductName nVARCHAR(100), B2B_GrossRevenue DECIMAL(10,2), B2B_DirectCost DECIMAL(10,2), B2B_NetRevenue DECIMAL(10,2), B2C_GrossRevenue DECIMAL(10,2)

问题 This question already has answers here : Pass An Instantiated System.Type as a Type Parameter for a Generic Class (6 answers) Closed 5 years ago . I have a class: public class MyClass<T> I have a config file that I am reading that has, say, Guid for the type T . How do I do this, except using the string from the config file instead of the actual type (instead of hard-coding Guid )? MyClass<Guid> = new MyClass<Guid>(); 回答1: You need the fully qualified type name: var typeArgument = Type

问题 I have been searching for an efficient algorithm to merge overlapping intervals on a dynamic array of intervals. For example, (start time, end time) wise, [(1, 2), (4, 8), (3, 10)] becomes [(1, 2), (3, 10)] after merging because (4, 8) and (3, 10) are overlapped. Overlapping means any part of the two intervals share the same moment. I know when a full array is given the operation can be done with a stack after sorting the intervals on start time ascending order (reference: geeksforgeeks). But

问题 I have mysql 2 tables: user_profile_field and user_profile_data with following columns: user_profile_field: -id (integer) -field (string) -category(string) user_profile_data: -id (integer) -user_id (integer) -field_id (integer) references user_profile_field(id) -data (string) I also have defined 2 Doctrine entities that map this relation. I need dynamicaly to create a form for updating user_profile_data. The form input type for each row of user_profile_field depends on user_profile_field
