OpCodes.Ldarga Field
Load an argument address onto the evaluation stack.
Namespace: System.Reflection.Emit
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:
Format | Assembly Format | Description |
|---|---|---|
FE 0A < unsigned int16 > | ldarga index | Fetch the address of argument indexed by index. |
The stack transitional behavior, in sequential order, is:
The address addr of the argument indexed by index is pushed onto the stack.
The ldarga instruction fetches the address (of type *) of the argument indexed by index, where arguments are indexed from 0 onwards. The address addr is always aligned to a natural boundary on the target machine.
For procedures that take a variable-length argument list, the ldarga instruction can be used only for the initial fixed arguments, not those in the variable part of the signature.
ldarga is used for by-ref parameter passing. For other cases, Ldarg and Starg should be used.
The following Emit method overload can use the ldarga opcode:
ILGenerator.Emit(OpCode, short)
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
