partial-classes

Are there are good uses of Partial Classes outside the webforms/winforms generated code scenarios? Or is this feature basically to support that? It is in part to support scenarios (WebForms, WinForms, LINQ-to-SQL, etc) mixing generated code with programmer code. There are more reasons to use it. For example, if you have big classes in large, unwieldy files, but the classes have groups of logically related methods, partial classes may be an option to make your file sizes more manageable. Code generation was the driving force behind partial classes. The need comes from having a code-generated

i'v a shopping_cart.aspx.cs file & also have a class file spcart.cs, shopping_cart.aspx.cs public partial class Ui_ShoppingCart : System.Web.UI.Page { public int tax = 0; public int subtotal = 0; public int granttotal = 0; protected void Page_Load(object sender, EventArgs e) { -------------------------/////some code } --------------------------------/////some code } spcart.cs public class Spcart { public void updatecart(int pid,int qty) { ---------/////some code } } now i want to set some values in class Ui_ShoppingCart variables tax, subtoal & granttotals from class Spcart, so i'd tried--> Ui

I have an autogenerated class from importing a web service containing something like this (abbreviated): [System.Runtime.Serialization.DataMemberAttribute()] public System.DateTime StartDate { get { return this.StartDateField; } set { /* implementation prop changed */ } } And I want to add an MVC format attribute to this member. So in another file containing the same partial class definition, I would like to do something like the following (which is illegal): [DisplayFormat(DataFormatString = "{0:dd-MM-yyyy}", ApplyFormatInEditMode = true)] public DateTime StartDate; A partial method is of no

I have defined a partial class with a property like this: public partial class Item{ public string this[string key] { get { if (Fields == null) return null; if (!Fields.ContainsKey(key)) { var prop = GetType().GetProperty(key); if (prop == null) return null; return prop.GetValue(this, null) as string; } object value = Fields[key]; return value as string; } set { var property = GetType().GetProperty(key); if (property == null) { Fields[key] = value; } else { property.SetValue(this, value, null); } } } } So that i can do: myItem["key"]; and get the content of the Fields dictionary. But when i

I defined a class: public class Sample{ public string name {get;set;} public int price {get;set} } Then Sample sampleA = new Sample(); sampleA.name = "test"; Sample sampleB = new Sample(); sampleB.price = 100; I do this because I will save JSONed sampleA and JSONed sampleB to Azure table, to present a full sample object. In other code, sometime only need name, sometime only need price, so I only need to pull data that needed each time. Of course in real code, the structure of the sample is much much more complex. My question is :, is there any easy method that can do: Sample sampleC = sampleA
