ldloc index |
Loads the local variable at index index onto stack. |
The stack transitional behavior, in sequential order, is:
- The local variable value at the specified index is pushed onto the stack.
The ldloc instruction pushes the contents of the local variable number at the passed index onto the evaluation stack, where the local variables are numbered 0 onwards. Local variables are initialized to 0 before entering the method only if the initialize flag on the method is true. There are 65,535 (2^16-1) local variables possible (0-65,534). Index 65,535 is not valid since likely implementations will use a 2-byte integer to track both a local's index, along with the total number of locals for a given method. If an index of 65535 had been made valid, it would require a wider integer to track the number of locals in such a method.
The ldloc.0, ldloc.1, ldloc.2, and ldloc.3 instructions provide an efficient encoding for accessing the first four local variables.
The type of the value is the same as the type of the local variable, which is specified in the method header. See Partition I. Local variables that are 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 overloads can use the ldloc opcode:
