在vs __asm中使用c ++内联asm

Question

char name[25];
int generated_int;

for(int i = 0; i<sizeof(name); i++)
{
    name[i] = (char)0;
}

cout << "Name: ";
cin >> name;

int nameLen = strlen(name);

__asm
{
    pusha;

    mov esi, &name //I got error here, I cant use "&". How to move name address to esi?
    mov ecx, nameLen
    mov ebx, 45

start:
    mov al, [esi]
    and eax, 0xFF
    mul ebx
    inc esi
    add edi, eax
    inc ebx
    dec ecx
    jnz start

    mov generated_serial, edi

    popa
}



cout << endl << "Serial: " << generated_serial << endl << endl;

我不知道如何在asm块中获取我的chay数组的地址.当我尝试使用"&"例如&name时我在编译时遇到错误:

error C2400: inline assembler syntax error in 'second operand'; found 'AND'

更新:

mov esi,name给我这个编译错误:C2443:操作数大小冲突

更新2:lea工作正常.

您似乎正在寻找lea指令,该指令将某些符号的有效地址加载到寄存器中.以下指令将存储namein 的地址esi.

lea esi, name
