Asp.net - Decimal.parse Fails For Currency String Created With String.Format?
Apr 5, 2011
I 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?

I've searched for the solution for this however 'answers'i've found have perhaps been a little more than I've needed. basically i have 2 textboxes on my form, 'textbox1' is populated by a value from a database, say.. 200.00 on form load. 'textbox2' needs to accept a users value (say 50.00) and then add/subtract that from the value in 'textbox1' when the form's refreshed/submitted/whatever
whats the syntax involved in this process, i've seen efforts involving parse, 'Cint' etc but need to check there isn't some ridiculously easy way of doing this..

So I need a format string to pass to String.Format that would "move" the decimal point.I can't perform any math operations before doing the String.Format, so it has to work right off the bat.Basically I'm emulating a formatting string from a proprietary server. In it if I say:
"MR2"
for the value:
12345
The result is:
123.45
I'm close with this, but it's not spot on:
String.Format("{0:#0.##}", 12345)
an extra, but not necessary... there is also MR2Z, which moves the decimal 2 left, but if the value is 0 "" is returned.

I need to give comma(,) for every thousends. So I used DataFormatString="${0:#,#}". It is working fine. But when value is 0. It is showing $00. I just want to show only $0.
How can we do that?

I am practicing for my next semester, trying to get ahead in VB.Net, so I got a library book and I am attempting the book exercises, in this exercise I need to replace the currency format to the To.String format, but everythiing I try doesnt work, and everything I read online just confuses me more, can anyone shed light on why my code is not outputting my discount amount and my total amount?
Dim subtotal As Decimal = Decimal.Parse(txtSubtotal.Text)
Dim discountPercent As Decimal = 0.25D
Dim discountAmount As Decimal = Math.Round(subtotal * discountPercent, 2)
Dim invoiceTotal As Decimal = Math.Round(subtotal - discountAmount, 2)

I have a DGV with a column bound to a Double. When I enter "1%" I get:
System.FormatException: Input string was not in a correct format.
I then try: MsgBox(System.Double.Parse("1%")) and get essentially the same error. (same for "$")
Is there a setting that will allow "$" & "%" as not only valid Double input but also do the correct adjustment for "%"?

format a decimal value to a string with a single digit after the comma/dot and leading spaces for values less than 100?For example, a decimal value of 12.3456 should be output as " 12.3" with single leading space. 10.011 would be " 10.0". 123.123 is "123.1" I'm looking for a solution, that works with standard/custom string formatting, i.e.
decimal value = 12.345456;
Console.Write("{0:magic}", value); // 'magic' would be a fancy pattern.

I have a program reporting 6.0054434322 gb Free on my machine.
Dim gigabytesC As String = (GetHDDFreeSpace(letterC) / 1024 / 1024 / 1024) & " gb"
I use string.format to try to chop off unwanted floating point numbers
Dim s As String
s = String.Format("{0:n3}", gigabytesC)
But.. The above line does not work.
Desired Result: s = 6.005 gb

As the title says I have a form with many databound textboxes. some of these boxes have data in them and some are empty. I need to add them altogether, so far all of the conversion methods I have tried err out when they run into an empty string, except Val, but then Val won't handle the string with a $ in it. I've tried decimal.parse which handles the $ but not the empty string. So I seem to be in circle that I can't get out of.

I realize the code listed below, whose serial port using string formatting which I inherited is complicated. It formats a Date obtained from a DatePicker control into a "yyyy-MM-dd HH:mm:ss" string format to send to a hardware device to be stored via Serial Port retrieves the date from the device and displays to user What I'm trying to do is port the code for use in a Socket rather than Serial Port which wants a Byte Arrray of the same Date Time string variable. I can't figure out how to encode and convert to Bytes the string value used in the Serial Port version. The evolution of the process is listed from top to bottom.

I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?

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?

I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.
