如何使用Boost库读取和写入（或修改）.ini文件？

为什么我用C#写这个:

for(int myVar = 0; myVar<10; myVar++)
{
//do something here
}

//then, if I try:
int myVar = 8;
//I get some error that the variable is already declared.

//but if I try:
Console.WriteLine(myVar);
//then I get the error that the variable is not declared.

我最常说的有点混乱.有谁知道为什么C#编译器会这样做？
