A plaster cast is a copy of a sculpture, which is cast in plaster. A plaster cast can accurately reproduce the details of the original sculpture, but is usually much less durable. It is often used as a stage in the casting process.
Concatenate Strings in C#: + Operator vs. String.Concat vs. StringBuilder. In the source code of almost any software application individual strings are concatenated into one string. To implement a string concatenation is thus something absolutely rudimentary and should belong to the repertoire of every software developer. In C# there are several options available to connect strings.
C# has two types of variables: value and object.. Variables of object type are stored on the heap. Value type variables are not. Value type variables behave rather like native variables in C++ (types like int), except that they are classes, and the values that are assigned to them are classes or structs. The way you can tell the difference between the two is that value type variables can take a literal.
