I'm new to C#.
I know in vb.net, i can do this:
Dim guid as string = System.Guid.NewGuid.ToString In C#, I'm trying to do
String guid = System.Guid.NewGuid().ToString; but i get an "Cannot convert method group 'ToString' to non-delegate type 'string'. Did you intend to invoke the method?" error.

A GUID is a 16-byte (128-bit) number, typically represented by a 32-character hexadecimal string.
An integer uses 32 bits, whereas a GUID is 128 bits - therefore, there's no way to convert a GUID into an integer without losing information, so you can't convert it back.
The Parse method trims any leading or trailing white space from input and converts the string representation of a GUID to a Guid value. This method can convert strings in any of the five formats produced by the ToString(String) and ToString(String, IFormatProvider) methods, as shown in the following table.
A GUID is a 128-bit integer (16 bytes) that can be used across all computers and networks wherever a unique identifier is required. Such an identifier has a very low probability of being duplicated.
According to MSDN the method Guid.ToString(string format) returns a string representation of the value of this Guid instance, according to the provided format specifier.
Examples:
guidVal.ToString() or guidVal.ToString("D") returns 32 hex digits separated by hyphens: 00000000-0000-0000-0000-000000000000 guidVal.ToString("N") returns 32 hex digits:00000000000000000000000000000000 guidVal.ToString("B") returns 32 hex digits separated by hyphens, enclosed in braces:{00000000-0000-0000-0000-000000000000} guidVal.ToString("P") returns 32 hex digits separated by hyphens, enclosed in parentheses: (00000000-0000-0000-0000-000000000000)
