i have to create an enum that contains values that are having spaces
public enum MyEnum { My cart, Selected items, Bill } This is giving error. Using concatenated words like MyCart or using underscore My_Cart is not an option. Please guide.
Thanks in advance.
From enum (C# Reference)
An enumerator may not contain white space in its name.
DisplayAttribute - See my marvelous answer to the question stackoverflow.com/questions/1101872/how-to-set-space-on-enum/…Enum just cant have space! What do you need it for? If you need it simply for display purpose, you can stick with underscore and write an extension method for your enum so that you can ask for the display text by doing this (assuming your ext method is call DisplayText). Internally you just implement the DisplayText method to substitute "_" with space
MyEnum.My_Cart.DisplayText(); // which return "My Cart" As per the C# specification, "An enumerator may not contain white space in its name." (see http://msdn.microsoft.com/en-us/library/sbbt4032.aspx) Why do you need this?
**
enums can't have spaces in C#!" you say. Here is the way System.ComponentModel.DescriptionAttribute to add a more friendly description to the enum values. The example enum can be rewritten like **
public enum DispatchTypes { Inspection = 1, LocalSale = 2,[Description("Local Sale")] ReProcessing=3,[Description("Re-Processing")] Shipment=4, Transfer=5 } Hence it returns "LocalSale" or "ReProcessing", when we use .ToString()
I agree the use of DisplayText if you are following convention. But if you need different display value to represent the enum constant, then you could have a constructor passing that value.
public enum MyEnum { My cart ("Cart"), Selected items("All Selected Items"), Bill("Payment");
private String displayValue; private MyEnum(String displayValue) { this.displayValue = displayValue; }
public String displayText() { return this.displayValue; }
}
You can have a displayText method or a toString method which would return the displayValue
