C# regular expression multi rows

[Sandason]

I have a multiple row string that i want to match from somewhere in the string to the first occurance of another word.

String = "Error Message: This is an error message and the error code for this is 443.
Error_ID = 999-Affd
Solution: Check mainTable 33."


So i want to grab "Error Message:" as the keyword to find then include all the text up to the word Solution
Something like:
Regex re = new Regex(@"Error Message:.*\n ??????", RegexOptions.IgnoreCase);
not sure what to put in for the ??????

Since you know that the string has to start with "Error Message"

you coud check it like

string theMessage ="";
If (errorString.StartsWith("Error Message") == true)
{
   theMessage = errorString.Replace("Error Message :","");
}

if you do want to use regular expression Im not sure how the regex would look like but will have to look something like

"$[E]{1}[r]{2}[o]{1}[r]{1}[ ]{1}[M]{1}[e]{1}[s]{2}[a]{1}[g]{1}[e]{1}"

but im not sure about it! (regular expression is not anywhere near my strong or weak point :P )

Thanks for your input, i already have the ability to grab all instances of "error message" and everything on the same line after it up to a new line but nothing that will grab everything afterwards with say 1 or 2 new lines ending with the word "solution" this is where my issue is.

String = "Error Message: This is an error message and the error code for this is 443.
Error_ID = 999-Affd
Solution: Check mainTable 33."

I think i found my solution
Regex re2 = new Regex(@"Error Message:.*?Solution", RegexOptions.Singleline);
