Need regular expression to validate email address also if user don't have email, user able to type 'No Email'. such that regular expression should validate 'No Email' as a valid string.
#"^(([\w\.\-]+)#([\w\-]+)((\.(\w){2,3})+)|(No Email))$"
You can combine your regex with an or expression |
var regex = "(.+#.+\..+|No Email)"

The validation part need some improvement (not RFC compliant) but you get the idea.

I have a event whose publish method has a signature as follows:
publish((string moduleName,object moduleData) payload)
I have a set up a mockEventAggregator and other necessary setups but I need to verify if it has been called once.
I am having a tough time trying to write the verify statement as the parameter seems a bit complex and confusing to me on how to implement it, as I'm not able to get the syntax right.
here's what I'm trying:
this.mockModuleEvent.Verify(x => x.Publish(It.IsAny<(string,object)>(), Times.Once));
You have wrong brackets. Move one bracket from the end after It.IsAny<(string,object)>()
this.mockModuleEvent.Verify(x => x.Publish(It.IsAny<(string,object)>()), Times.Once);

I have the following code in VBA and wish to convert it to C#
Format(Now(), "m-d-yyyy HAM/PM")
Being pretty green with C# syntax I used the following tool
It gave me the following:
Strings.Format(DateTime.Now(), "m-d-yyyy HAM/PM");
Visual Studio is telling me Strings and Now is wrong.
Please tell me what did I miss here.
Format(Now(), "m-d-yyyy HAM/PM") formats the current date & time according to a time format. The equivalent in C# would be transforming it to a string, since formatting a string is a different operation:
DateTime.Now.ToString("M-d-yyyy htt")

I have a string and when I try to convert that to a DateTime it's throwing an error. Why?
string str = "3/23/2016 5:10:32 PM";
datetime= convert.ToDateTime(str);
Convert.ToDateTime should work fine if your current culture allows this.
You however have some strange characters in your string... I have copied and pasted it and it didn't work, however writing it directly did.
Check it in a fiddle: https://dotnetfiddle.net/l5nzso
It seems you have some left-to-right mark (0x200E) Unicode characters scattered between the characters in your string. Check it in this other fiddle

I am trying to replace a string content with another but it does not replace
string oldValue= "iif([PricingTKt_US]>0,1-([F221-B01]/iif([PricingTKt_US]=0,1, [PricingTKt_US])),0)";
oldValue=oldValue.Replace("[PricingTkt_US]","[F123]")
Please help me to understand the mistake I am doing.
string oldValue= "iif([PricingTKt_US]>0,1-([F221-B01]/iif([PricingTKt_US]=0,1, [PricingTKt_US])),0)";
PricingTKt_US Capital K.
oldValue=oldValue.Replace("[PricingTkt_US]","[F123]")
PricingTkt_US Small k

I cannot seen to find out the purpose of the ^ in a C# method call.
For example:
SomeObject::somemethod(ObjArg^ arg)
{
// method body
}
What is the effect of the ^?
This is not C#. This is C++/CLI. The ^ is the Handle to Object Operator. It is used here to indicate that arg is a handle to a managed class of type ObjArg.
