Transfers control to a target instruction (short form) if value is true, not null, or non-zero.
[Visual Basic] Public Shared ReadOnly Brtrue_S As OpCode [C#] public static readonly OpCode Brtrue_S; [C++] public: static OpCode Brtrue_S; [JScript] public static var Brtrue_S : OpCode;
The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
|2D < int8 >||brtrue.s target |
|Branch to a target instruction at the specified offset if non-zero (true), short form.|
The stack transitional behavior, in sequential order, is:
- value is pushed onto the stack by a previous operation.
- value is popped from the stack; if value is true, branch to target.
The brtrue.s instruction transfers control to the specified target instruction if value (type natural int) is nonzero (true). If value is zero (false) execution continues at the next instruction.
If value is an object reference (type O) then brinst (an alias for brtrue) transfers control if it represents an instance of an object (for example, if it is not the null object reference; see Ldnull).
The target instruction is represented as a 1-byte signed offset from the beginning of the instruction following the current instruction.
Control can only be transferred to the first of these prefixes if the target instruction has one or more prefix codes. Control transfers into and out of try, catch, filter, and finally blocks cannot be performed by this instruction.
The following Emit constructor overload can use the brtrue.s opcode:
