Description

01

break

inform a debugger that a breakpoint has been reached.

No evaluation stack behaviors are performed by this operation.

The break instruction is for debugging support. It signals the CLI to inform the debugger that a break point has been tripped. It has no other effect on the interpreter state.

The break instruction has the smallest possible instruction size enabling code patching with a break point and generating minimal disturbance to the surrounding code.

The break instruction can trap to a debugger, do nothing, or raise a security exception. The exact behavior is implementation-defined.

The following Emit method overload can use the break opcode:

  • ILGenerator.Emit(OpCode)
