Remarks
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 |
|---|---|---|
| 02 | ldarg.0 | 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:
