Converts the value on top of the evaluation stack to unsigned int16
, and extends it to int32
.

Public Shared ReadOnly Conv_U2 As OpCode
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 |
---|---|---|
D1 | conv.u2 | Convert to int16 , pushing int32 on stack. |
The stack transitional behavior, in sequential order, is:
value
is pushed onto the stack.value
is popped from the stack and the conversion operation is attempted.If the conversion is successful, the resulting value is pushed onto the stack.
The conv.u2
opcode converts the value
on top of the stack to the type specified in the opcode, and leave that converted value on the top of the stack. Integer values of less than 4 bytes are extended to int32
when they are loaded onto the evaluation stack (unless conv.i
or conv.u
is used, in which case the result is also native int
). Floating-point values are converted to the F
type.
Conversion from floating-point numbers to integer values truncates the number toward zero. When converting from an float64
to an float32
, precision can be lost. If value
is too large to fit in a float32 (F)
, positive infinity (if value
is positive) or negative infinity (if value
is negative) is returned. If overflow occurs converting one integer type to another, the high order bits are truncated. If the result is smaller than an int32
, the value is sign-extended to fill the slot.
If overflow occurs converting a floating-point type to an integer the value returned is unspecified.
No exceptions are ever thrown when using this field. See Conv_Ovf_I2 and Conv_Ovf_I2_Un for equivalent instructions that will throw an exception when the result type can not properly represent the result value.
The following Emit method overload can use the conv.u2
opcode:
