Const string vs static readonly string

     STATIC_READONLY_STRING =    CONST_STRING = 

Compile and run:
C: \ Users \ de \ Desktop \ bao> csc/t: library/nologo ClassA1.cs

C: \ Users \ de \ Desktop \ bao> csc/r: ClassA1.dll/nologo ClassB1.cs

C: \ Users \ de \ Desktop \ bao> ClassB1
ClassA1.CONST _ STRING = CONST_STRING
ClassA1.STATIC _ READONLY_STRING = STATIC_READONLY_STRING

C: \ Users \ de \ Desktop \ bao>

Reedit ClassA1.cs

     STATIC_READONLY_STRING =    CONST_STRING = 

Recompile classa1.csand run classb1.exe:
C: \ Users \ de \ Desktop \ bao> csc/t: library/nologo ClassA1.cs

C: \ Users \ de \ Desktop \ bao> ClassB1
ClassA1.CONST _ STRING =
ClassA1.STATIC _ READONLY_STRING =

C: \ Users \ de \ Desktop \ bao>

????

Decompress classb1.exe

C: \ Users \ de \ Desktop \ bao> ildasm

C: \ Users \ de \ Desktop \ bao>

After classb1.exe is opened, view/metainfo/show! (Ctrl + M)

There is such a section at the bottom of metainfo:

User Strings
-------------------------------------------------------
70000001: (64) L "ClassA1.CONST _ STRING = {0} \ r \ nClassA1.STATIC _ READONLY_STRING = {1 }"
70000084: (12) L ""

And the IL code corresponding to ClassB1.ShowClassA1

. Method public hidebysig static void ShowClassA1 () cel managed
{
// Code size 23 (0x17)
. Maxstack 8
IL_0000: nop
IL_0001: ldstr "ClassA1.CONST _ STRING = {0} \ r \ nClassA1.STATIC _ READONL"
