Can't set breakpoints on an auto-property setter ? Why?

由 て烟熏妆下的殇ゞ 提交于 2019-11-27 01:31:24
问题 Apparently VS 2008 does not allow setting a breakpoint just on the setter of an auto-property. I.e. if I define an auto-property like this: public int CurrentFramesize { get; protected set; } and then try to set a breakpoint on the setter line, the whole auto-property turns breakpoint-red. This works just fine for normal properties, so any idea why auto-properties get this special (restrictive) treatment? Are they more than just syntactic sugar to normal properties with a hidden backing field

C# automatic property deserialization of JSON

由 可紊 提交于 2019-11-26 22:26:34
I need to deserialize some JavaScript object represented in JSON to an appropriate C# class. Given the nice features of automatic properties, I would prefer having them in these classes as opposed to just having fields. Unfortunately, the .NET serialization engine (at least, by default) totally ignores automatic properties on deserialization and only cares about the backing field, which is obviously not present in the JavaScript object. Given that there's no standard way to name backing fields and to be honest I don't even want to bother with the "let's create a JavaScript object that looks

Automatically implemented property in struct can not be assigned

问题 I have a next code: struct T { public T(int u) { this.U = 10; //Errors are here } public int U { get; private set; } } C# compiler give me a pair of errors in stated line: 1) Backing field for automatically implemented property 'TestConsoleApp.Program.T.U' must be fully assigned before control is returned to the caller. Consider calling the default constructor from a constructor initializer. 2) The 'this' object cannot be used before all of its fields are assigned to What I do wrong? Help me

How to find out if a property is an auto-implemented property with reflection?

由 心已入冬 提交于 2019-11-26 11:14:49
问题 So in my case i am doing discovery of the structure of a class using reflection. I need to be able to find out if a property is an auto-implemented property by the PropertyInfo object. I assume that the reflection API does not expose such functionality because auto-properties are C# dependent, but is there any workaround to get this information? 回答1: You could check to see if the get or set method is marked with the CompilerGenerated attribute. You could then combine that with looking for a

Initializing C# auto-properties [duplicate]

问题 This question already has an answer here: What is the best way to give a C# auto-property an initial value? 21 answers I\'m used to writing classes like this: public class foo { private string mBar = \"bar\"; public string Bar { get { return mBar; } set { mBar = value; } } //... other methods, no constructor ... } Converting Bar to an auto-property seems convenient and concise, but how can I retain the initialization without adding a constructor and putting the initialization in there? public

What are Automatic Properties in C# and what is their purpose?

由 穿精又带淫゛_ 提交于 2019-11-26 01:43:09
问题 Could someone provide a very simple explanation of Automatic Properties in C#, their purpose, and maybe some examples? Try to keep things in layman\'s terms, please! 回答1: Automatic Properties are used when no additional logic is required in the property accessors. The declaration would look something like this: public int SomeProperty { get; set; } They are just syntactic sugar so you won't need to write the following more lengthy code: private int _someField; public int SomeProperty { get {

What is the best way to give a C# auto-property an initial value?

由 …衆ロ難τιáo~ 提交于 2019-11-26 01:19:27
问题 How do you give a C# auto-property an initial value? I either use the constructor, or revert to the old syntax. Using the Constructor: class Person { public Person() { Name = \"Initial Name\"; } public string Name { get; set; } } Using normal property syntax (with an initial value) private string name = \"Initial Name\"; public string Name { get { return name; } set { name = value; } } Is there a better way? 回答1: In C# 5 and earlier, to give auto implemented properties an initial value, you

C# 3.0 auto-properties — useful or not? [closed]

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 5 years ago . Note: This was posted when I was starting out C#. With 2014 knowledge, I can truly say that auto-properties are among the best things that ever happened to the C# language. I am used to create my properties in C# using a private and a public field: private string title;

Difference between Property and Field in C# 3.0+

问题 I realize that it seems to be a duplicate of What is the difference between a Field and a Property in C#? but my question has a slight difference (from my point of view): Once I know that I will not use my class with \"techniques that only works on properties\" and I will not use validation code in the getter/setter. Is there any difference (except the style/future development ones), like some type of control in setting the property? Is there any additional difference between: public string
