[C++]
public: static OpCode Ldstr;
[JScript]
public static var Ldstr : 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
72 < T > ldstr mdToken Pushes a string object for the metadata string token mdToken.

The stack transitional behavior, in sequential order, is:

  1. An object reference to a string is pushed onto the stack.

The ldstr instruction pushes an object reference (type O) to a new string object representing the specific string literal stored in the metadata. The ldstr instruction allocates the requisite amount of memory and performs any format conversion required to convert the string literal from the form used in the file to the string format required at runtime.

The Common Language Infrastructure (CLI) guarantees that the result of two ldstr instructions referring to two metadata tokens that have the same sequence of characters return precisely the same string object (a process known as "string interning").

The following Emit constructor overload can use the ldstr opcode:

  • ILGenerator.Emit(OpCode, string)
