TBitConverter provides two main class functions:

• converts a value in a Delphi native type into an array of bytes.
• converts an array of bytes into a Delphi native type.

class function ToInteger(Value: TArray<Byte>): Integer;

C++

__classmethod int __fastcall ToInteger(System::DynamicArray<System::Byte> Value);

 

System.Types.TBitConverter.InTo     From RAD Studio API Documentation 

Delphi

class function InTo<T>(const B: TArray<Byte>; Offset: Integer = 0): T;

static;C++

__fastcall TBitConverter::InTo(const System::DynamicArray<System::Byte> B, int Offset)

<T>必须是明确的类型 

Data := TBitConverter.InTo<double>(Buffer);
