I am using standard String.Format method. It is using numeric objects.
Console.WriteLine("obj1 = {0} and obj2 = {1}", "obj1", "obj2");
I want to use named indexes.Like this
Console.WriteLine("obj1 = {o1} and obj2 = {o2}",
new { o1 = "obj1", o2 = "obj2"});
How I can use same last code?
I'm trying to format a column of numbers is a datagridview and I'm having some problems. This is the code I'm using: dgv.Columns(5).DefaultCellStyle.Format = "n2" If the number I put in the cell is 100.50, it shows up as 100.00. If I try to edit it back to 100.50, I get a "value was either too large or too small for an Int32" error. The cell also is accepting Char data. I want to format the column so it only accepts numbers in a '#####.##' format.

View 7 RepliesI have a series of files numbered from 1-80 I want to duplicate every 4th file of the series and have the numeric value pushed so that the 80 files become 100. I tried a For Loop going to 80 but for some reason I can't figure a good way out to push the value so that the next item in the list doesn't overwrite the last.My goal is to have the files copied from an original destination to a new one but with their name to be pushed up from its original.
View 1 RepliesI have some VB .NET software that interfaces to a load of old (but sound) COM objects. The VB provides a GUI for the COM objects, part of which consists of setting various options on the COM objects - several of which relate to string formatting.I have a simple pair of VB .NET functions that convert basic %f, %d, %g formats to/from .NET equivalents using a large select case covering specific common strings, but they don't cover all formats.[code]Before I start diving in and making it more versatile with some parsing, does anyone know of a class (eg VB or C# .NET) that provides a decent ready-made implementation? Or perhaps some regexp wizadry could be used?

Why? They are both effectively a function pointer (or delegate?) to a function that accept a string and return a string.

How do you do this using string.format?
I know Val() is a VB6 function, but one thing I like about it is that you can wrap a string in it and it will "extract" the numerical value from the string if there are other things present (i.e. Val("123 Main St.") returns 123). This is the way my teacher taught us to use it. I know about the .TryParse and .Parse methods of the different data types, and how those can be used to check for a numerical value, but is there a replacement that can strip any non-numeric value from a string to put it in an integer (or double, single, decimal, etc.)?
View 14 Repliesis there a way to check if a string contains characters other than numeric? ive used isnumeric quite a bit and its pretty usefull, but cant find a way to check for text in a string. Having searched around theres a few ways of doing it slowly that ive found using an array of letters and a loop / instring, but thats much more hassle than checking for numbers, so strikes me there must be a way.

I used a regular expression, which handles both numbers and letters in strings of arbitrary length, in one line of code.
dim rtn as String = Regex.Replace(input, "..", "$& ")
I'd like to take numeric strings of arbitrary length and insert a space every 2 characters.
So 1233456 becomes 12 33 45 6. Is there a way I can use format as string or IFormatProvider, like? That would put a limit on how long the string could be though, right? Since I'm casting to a long.

I have a sql table with the following fields
ID = PrimaryKey (nvarchar(50))
Name Surname
sample value of ID = RHO-1 How do i automatically increment the numeric portion when adding a new record to the database eg: RHO-2, RHO-3 and so on.
I'm using Entity Framework code first and pulling some data back from our database. In the table I'm accessing is 13 columns that store the number of a items a customer purchased per week for the last 13 weeks as a char field. I have no control over how this data is stored. I need to total the 13 weeks results together to get a combined total, so take week1 + week2 + week3.... = Total Items Purchased over 13 weeks.In SQL I'd just Cast the char to an Integer and add the values together. But I'm struggling finding a solution to do this in linq.
