ILGenerator: How to add boolean to the stack

Question

Here is the way I can put float value to the stack(in C#):

ILGenerator gen = method.GetILGenerator();
gen.Emit(OpCodes.Ldc_R4, (float)12.5);

How can I put boolean value to the stack by using Emit method?

Answer 1

There is no representation of a boolean value on the evaluation stack. The bool, char, byte, ushort, uint, and their signed variants are all represented as a 4-byte signed integer (i4).

True:

ldc.i4.1

False:

ldc.i4.0
