C# - Using String.Format To Build Regular Expressions: "Input String Was Not In A Correct Format"
Mar 7, 2011
I'm bulding document-from-template engine. At certain points I need to match on Reg Exp groups and replace template text with content from a db.
I 'hardcoded' my RegExp initially, doing something like: Regex r = new Regex(@"{DocSectionToggle::(?<ColumnName>w+)::(?<ResponseValue>.+)}[[(?<SectionContent>.+)]]", RegexOptions.Multiline);
it does group capture, so the syntax isn't the prettiest.
Just to make things neater and because I want' to keep the patterns in web.config or elsewhere, I've 'evolved' algorithm to something like:
[code]...
But I'm getting an error: 'Input string was not in correct format'.
I've completed the 22 first tutorials of the data access tutorials, and now I'm trying to apply these techniques to a project I started myself.But i'm stuck trying to replace an id by its value from another table, so I want to show all information about a car ("wagen") , but instead of showing "1" as driver ("chauffeur") I want to show his name.I've written this querry for the "wagen" table in the dal
As far as I can tell, I've got the input string in an acceptable format (It's pulling a number that is the value from the Agent dropdownlist) and I'm even having the code convert the value to Int32. The database column is set to "int" and the DAL and BLL both reinforce this. Am I missing something? I can't post everything because the sensitive nature of some of the code, but here's some of what I've got.

when i run this code it says Input String not in correct format, if i pass null values for all the parameters , I am using Linq to sql and If i execute the stored proc with null values in the database it works fine, it does not let me pass null values from the C sharp page.
I have a field in my products table called dProductPrice which is a datatype of money. In my datalist i need to display the field as currently it shows price as e,g, 1.3500 but i need it to 2 decimal places so it is 1.35? in my datalist i have done this using the format as well
Is it legal to define a default value for a parameter the way I am in the code below? It keeps throwing an "Input string was not in a correct format." error for me. Is there a different way I should be doing this?

My code is working fine if the statement (numtickets > tickav) is true (if tickets available is greater than tickets ordered) But if other wise, it throws in this error "FormatException was unhandled by user code, Input string was not in a correct format" on int numTick = Convert.ToInt32 (txtNumber OfTickets. Text);
I get the following error when I run my application. It was working fine in 3.5. I am facing this issue when we migrated to .Net 4.0. Has anything changed in 4.0 types or something else which is causing this?

DataRow dr = GetCurrentEvents(int.Parse(Request.QueryString["ScheduleID"]));
ScheduleID is an int in my stored procedure. SoI inserted the (int.Parse) But now I get that error. How can I convert an int into the QueryString.?If I take out the (int.Parse) The method I have calling the above. Its something like:
private DataRow GetCurrentEvents(int ScheduleID)
{
some stuff
}
If I change it to (string ScheduleID). I get a different error bc I'm trying to convert an nvarchar to an int...
I'm using Routing in web forms I try to use Page.RouteData.Values["Id"]; its a string I need the Id for a querys and for navigation so I've tried
GetProductById(Id); object departIdString = Page.RouteData.Values["Id"]; string d = (string)departIdString;[code]...
at System.Convert.ToInt32(Object value)I've run out of ways to try the funny thing is it all works I get the Id out of the RouteData and hit The data base just fineit works all through the app. but it will fill up an elmah error log right quick and I don't think it should happen
