OpCodes.Ldc_I4 Field

Definition

Namespace:

System.Reflection.Emit

Assemblies:

netstandard.dll, System.Reflection.Primitives.dll

Source:

OpCodes.cs

Pushes a supplied value of type int32 onto the evaluation stack as an int32.

C#

public static readonly System.Reflection.Emit.OpCode Ldc_I4;

Field Value

OpCode

Remarks

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
20 < int32 >	ldc.i4 num	Pushes the value num onto the stack.

The stack transitional behavior, in sequential order, is:

1. The value num is pushed onto the stack.

Note that there are special short (and hence more efficient) encodings for the integers -128 through 127, and especially short encodings for -1 through 8. All short encodings push 4 byte integers on the stack. Longer encodings are used for 8 byte integers and 4 and 8 byte floating-point numbers, as well as 4-byte values that do not fit in the short forms. There are three ways to push an 8 byte integer constant onto the stack

1. Use the Ldc_I8 instruction for constants that must be expressed in more than 32 bits.

2. Use the Ldc_I4 instruction followed by a Conv_I8 for constants that require 9 to 32 bits.

3. Use a short form instruction followed by a Conv_I8 for constants that can be expressed in 8 or fewer bits.

The following Emit method overload can use the ldc.i4 opcode:

• ILGenerator.Emit(OpCode, Int32)
