I have a list of strings:
var listOfStrings = new List<string>{"Cars", "Trucks", "Boats"};
and I have a vehicles options which has a Name field.I want to find the vehicles where the name matches one of the items in the listOfStrings.I'm trying to do this with linq but can't seem to finish it at the moment.

Im trying to test my extension method that converts a list of strings in a string comma separated:
public static class Extensions
{
public static string ToCommaString<T>(this IList<T> input)
{
StringBuilder sb = new StringBuilder();
foreach (T value in input)
{
sb.Append(value);
sb.Append(",");
}
return sb.ToString();
}
public void TestExtension()
{
IList test=new List<string>();
//test.ToCommaString doesnt appear
}
}
The issue is that in the method TestExtension i cant use ToCommaString method. Do you know what's happening?
Could i make available for all my web application this extension method registering in web.config or something similar?
When I press F5 (debug) in Visual Studio 2010 Express, I get the following error message:
Unable to start debugging on the web server. IIS does not list a web site that matches the launched URL.
This happens only when I am trying to make use of the option "Use custom server".
I got both the host file and the IIS bindings set up. The server that I specified is working in the browser.
I have an HTML text that I get from
WebResponse webResponse = Req.GetResponse();
now all i need it text between "<ol>" and "</ol>" tags.
how would i get this using regular expressions?
Given a string like:
Token A^*!%~Token B^*!%~Token C^*!%~Token D^*!%~Token E
Write a method that parses the string into a series of substrings where the delimiter between the substrings is ^*!%~ and then reassembles the strings and delimiters into a single new string where each of the substrings is in the reverse order from the original string. The method must return the final string. The expected output would be:
Token E^*!%~Token D^*!%~Token C^*!%~Token B^*!%~Token A
I found that I don't need to use jQuery or AjaxToolKit to use a textbox with autocomplete instead using the AutoCompleteType() class.However, base in the documentation it says the autocomplete will just trigger after the button was click at first instance, with that
description looks like what I want to do will not be applicable.Is it possible to populate the textbox with a list of strings in page load? so that if I type in a textbox it will give me a complete list of strings already.

View 2 RepliesI'm developing an sms application in c#. The service that I use to send a message only allows characters form the 7 bit alphabet. I'm looking for a way to check if a message only contains characters from this alphabet.
My first idea was to split the message into a character array and then loop these characters and compare them to the alphabet. But I bet there is a much better.

View 2 RepliesList<ThemeObject> themeList = (from theme in database.Themes

from item in resultSet
select new ThemeObject { Name = theme.Name, ImageID = item.imageID}).ToList();
dgvGridView.DataSource = themeList;
dgvGridView.DataBind();
The list object populates fine. The datagrid is setup with 2 columns. A textbox column for the "Name" which is bound to "Name" An image column which is bound to the "ImageID" field. When I execute the code I receive the following error on the DataBind() Could not determine a MetaTable. A MetaTable could not be determined for the data source '' and one could not be inferred from the request URL. Make sure that the table is mapped to the dats source, or that the data source is configured with a valid context type and table name, or that the request is part of a registered DynamicDataRoute. I'm not using any dynamicdataroutes as far as I can tell. Has anyone experienced this error before?

Split the input string based on the separator list passed. Returned string list should have separators in it.
.NET API needs to be implemented
string [] SplitWithSeparators( string inputText, string[] separators)
Input
inputText: passed string
RAMESH EMPCODE 001 SURESH EMPCODE 002 GIRISH EMPCODE 003
Separators: passed string[]
string [0] : TRINATH
string [1] : SHARATH
string [2] : SRIDHAR
THIS OUTPUT I SUPPOSE TO GET
Output
string [0] : TRINATH EMPCODE 001
string [1] : SHARATH EMPCODE 002
string [2] : SRIDHAR EMPCODE 003
