How can I do the following in C# :
var re = /^\d{4}(\/\d{2}){2} \d{2}(:\d{2}){2}$/;
re.test('2013/03/05 15:22:00'); // returns true
You can use the Regex.IsMatch instead (docs).
Regex.IsMatch("2013/03/05 15:22:00", #"^\d{4}(\/\d{2}){2} \d{2}(:\d{2}){2}$"); // true if match
The below code should get you where you want to be.
Regex rx = new Regex(#"^\d{4}(\/\d{2}){2} \d{2}(:\d{2}){2}$");
String test = "2013/03/05 15:22:00";
if (rx.IsMatch(test))
{
//Test String matches
}
else
{
//Test String does not match
}

In my class partData the FW_Step attribute isfrom the type double?
When I try to format it like that
partData.FW_Step.Value.ToString("F3")
It's fail when the value is null
How can I use the format when the value is null?
You can't format when it's null; hopefully the reasons why are obvious. You need to check for the value first:
string formattedValue;
if (partData.FW_Step.HasValue)
formattedValue = partData.FW_Step.Value.ToString("F3");
else
formattedValue = "default value for null";
You can make this code shorter using a ternary expression:
string formattedValue = partData.FW_Step.HasValue ? partData.FW_Step.Value.ToString("F3") : "default value for null";

The input string: A+SUM(A)C+AB-C+SUM(A)+1
I want to replace A with 0, the result like this:0+SUM(A)C+AB-C+SUM(A)+1
or replace SUM(A) with 0, the result like this:A+SUM(A)C+AB-C+0+1
Thanks
Without Regex (because Regex is overkill for this):
var s = "A+SUM(A)+B-C";
var replaceBeginningA = s.Replace("A+", "0+");
var replaceSumA = s.Replace("SUM(A)", "0");
Console.WriteLine(replaceBeginningA); // 0+SUM(A)+B-C
Console.WriteLine(replaceSumA); // A+0+B-C
As pointed out in the comments though, you need to provide more detail if this input is expected to have a different format.
maybe:
replace ^A with 0
replace SUM\(A\) with 0
Try thus:
string replaced = Regex.Replace(input, #"\b(\w+)\+SUM\(\1\)", "0+0");
This will match anything of the form
foo+SUM(foo)
and replace it with 0+0

How do i find SiteMap.RootNode.ChildNames title's value equel 'test' in one line?
I don't write linq it doesn't work.
protected SiteMapNodeCollection getParentNodeTitle()
{
SiteMap.RootNode.ChildNames
}
This should do the trick:
var mySiteMap = new SiteMap();
/* Lots of code for populating your SiteMap here */
var nodeTitledTest = mySiteMap.RootNode.ChildNodes.Where(x => x.Title == "test").FirstOrDefault();
This will return the first node with a title equal to "test" or null if no such node could be found.

I have an array of words and I want to remove them from an input string, could anyone tell me what is the better way to conduct this task?
This should work
string[] arrToCheck = new string[] { "try ", "yourself", "before " };
string input = "Did you try this yourself before asking";
foreach (string word in arrToCheck )
{
input = input.Replace(word, "");
}
MessageBox.Show("result is "+input);
input variable will now have a string which does not have those words in your array.

I have if else condition in one function in oracle
i need to convert that into c# code please help.
IF INSTR( pString, pSeparator, -1, 1) != ( LENGTH( RTRIM( pString )) - LENGTH( pSeparator ) + 1 )
THEN
-- There isn't one at the end so add it
l_Return := pString || pSeparator;
--DBMS_OUTPUT.PUT_LINE('Did not find seperator - ADDING');
In this case you can use string.EndsWith() instead, that's exactly what you are trying to check:
if(!pString.EndsWith(pSeparator))
{
//There isn't one at the end so add it
}
