Assembly: mscorlib (in mscorlib.dll)
The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
Load argument 0 onto stack
The stack transitional behavior, in sequential order, is:
The argument value at index 0 is pushed onto the stack.
The ldarg.0 instruction is an efficient encoding for loading the argument value at index 0.
The ldarg.0 instruction pushes the argument indexed at 0 onto the evaluation stack. The ldarg.0 instruction can be used to load a value type or a primitive value onto the stack by copying it from an incoming argument. The type of the argument value is the same as the type of the argument, as specified by the current method's signature.
Arguments that hold an integer value smaller than 4 bytes long are expanded to type int32 when they are loaded onto the stack. Floating-point values are expanded to their native size (type F).
The following Emit method overload can use the ldarg.0 opcode:
Windows 98, Windows 2000 SP4, Windows Millennium Edition, Windows Server 2003, Windows XP Media Center Edition, Windows XP Professional x64 Edition, Windows XP SP2, Windows XP Starter Edition
