如何读取C#中指针的值并将其转换为字符串

来自MSDN（注意，应该使用/unsafe开关编译）

int number;
unsafe 
{
    // Assign the address of number to a pointer:
    int* p = &number;
    // Commenting the following statement will remove the
    // initialization of number.
    *p = 0xffff;
    // Print the value of *p:
    System.Console.WriteLine("Value at the location pointed to by p: {0:X}", *p);
    // Print the address stored in p:
    System.Console.WriteLine("The address stored in p: {0}", p->ToString());
}
// Print the value of the variable number:
System.Console.WriteLine("Value of the variable number: {0:X}", number);

通过调用&[变量名称]指针类型为[变量类型]*

long number = 3;
long* ptr = &number;

您可以更改指针的类型。这可能会以非常肮脏的结局结束。

int* dirtyPtr = ((int*)ptr) + 1; //Takes only the second half of the long(8 Bytes) as int(4 Bytes)
// +1 refers to the length to the type, so you go 4 Bytes ahead

您可以使用*[指针名称]=值更改指针后面的变量值

*dirtyPtr = 50;
