Caller information gives information about the caller of any function. This concept was introduced in C# 5.0 . These three types of attributes that are used in tracking information.. CallerFilePath: Sets the information about caller’s source code file. CallerLineNumber: Sets the information about caller’s line number.
What is an attribute C#?

Is Unsafe code faster?
The specification implies unsafe code is inherently faster with pointers. The subsequent elements of the fixed size buffer can be accessed using pointer operations from the first element. Unlike access to arrays, access to the elements of a fixed size buffer is an unsafe operation and is not range checked.
