How can I parse a string in VB.NET to enum value?Example I have this enum:
Public Enum Gender
NotDefined
Male
Female
End Enum
how can I convert a string "Male" to the Gender enum's Male value?
I have a URL lets say . some time i need to send HTTP and some time i need to send it to HTTPS for that i created a enum:
Private _protocol As Protocol
Enum Protocol
HTTP
HTTPS
[CODE]...
Now when i get value back from protocoltype it returns me integer value as enum do so tell me how to get string from enum or other substitute.
Dim targetUri As String = setting.protocolType & "://www.mysite.com"
I know this is a proper enum:
Private Enum Months
JANUARY = 1
FEBRUARY = 2
...
End Enum
However, I want to have an enum where the string will solely be integers.
Example:
Private Enum ColumnCounts
01 = 5
02 = 4
03 = 40[code].....
Essentially, I didn't want to put the f in there, just wanted to do 01. The way this will be called is:
Select Case (nRecordType)
Case "01"
...
Case "02"[code].....
Because I'm not making an instance of it and not calling a constructor, there's no way to autopopulate a Dictionary.And I don't want to convert to integer so I'm not going to do an array. That is just in case eventually the value gets above 99 and the next value would be A0.I'm trying to think of easy future changes to this and backwards compatability.If you need more explanations, let me know.
Edit 2:This is what I've done now and I think it should work:
Public Class Part
Private Shared columnCounts As Dictionary(Of String, Integer) = New Dictionary(Of String, Integer)
Public Shared Function ValidateColumns(ByRef lstFiels As List(Of String)) As Boolean[code]....
I can't verify that it's going to do what I want to, but it doesn't give me an error when I build it so I'm crossing my fingers.

View 8 RepliesI have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?

View 3 RepliesI was wondering if there was a way to directly convert the integer DayOfWeek returns into a string representing the day like Monday, Tuesday etc.
Sample code:
MessageBox.Show(Date.Today.DayOfWeek)
This will return 6 (as of today). Is there a way to directly convert this into Saturday, for example? I don't really care what it really converts it into, but I want to do away with my Select Case:
Select Case Date.Today.DayOfWeek
Case 1
day = "Monday"

I have written a program that uses an array of the english alphabet and Morse code. I also built a form with a input box for the alphabetic information and an output box with the Morse Code. What i am trying to do is basically type a word like "Hi" in the input box and produce the Morse Code equivalent in the Morse Code output box. [Code] This works but only one letter at a time. Do i need to Parse the string of characters one at a time, and then run it through a loop like i have created?

View 4 RepliesWhich is better, using a nullable enum or adding the value None=0 to your enum list?Using nullables requires more code, but I kind of like it since it forces me to think about the possibility. Otherwise I'm liable to forget about the None enum and fail to account for it being a special case.

I am making a change to an existing process. Currently the csv file (which can have embedded "," with the field in quotes), i being passed as an
IO.StreamReader parameter pStreamReader.
dim vLine as string = pStreamReader.ReadLine
dim vFields () as String = vLine.Split(","c)
Well ... obviously the split does not work with embedded commas in a field. Looked at TextFieldParser, but it is in the FileIO class and the module is passed a IO.StreamReader. Can it work?
Or how abour a RegEx? Does anyone have any suggestions? I have look around on the internet and it seems like a common questions with a bunch of wild goose chases.

I would like to parse a string to extract embedded parameters. [code]...

I am writing a VB.NET application which needs to extract data from an XML document. The Dataset.ReadXML function would be suitable, if the XML document was held in a disk file. However I would prefer the XML document to be passed via a string property of my class object, not as a disk file.
Is there a way to make the ReadXML function take its input from a string instead of a file ? If not, are there other functions which can be made to parse XML which is held as a string.?
