C＃在应用程序中保存文件位置(C# Saving file location within application)

 我看起来像一个错误，我设法用更简单的代码重现这个问题： 
 
fn main() {
    let mut vector = vec!(1u, 2u);
    for &x in vector.iter() {
        let cap = vector.capacity();
        println!("Capacity was: {}", cap);
        vector.grow(cap, &0u); // be sure to cause reallocation
        *vector.get_mut(1u) = 5u;
        println!("Value: {}", x);
    }
}
 
 它输出： 
 
Capacity was: 4
Value: 1
Capacity was: 8
Value: 2
 
 我正在修改向量内容并重新分配，导致底层切片引用未分配的内存（ vector.iter()实际上是vector.as_slice().iter() ）。 
 
 它看起来像是最近的变化，由于双重借用而无法在生锈0.11上编译。 
 
 我在这里打开了一个问题： https ： //github.com/rust-lang/rust/issues/16820 
 
 编辑（2014年9月10日）：该错误现已更正： https ： //github.com/rust-lang/rust/pull/17101 

I looks like a bug, I managed to reproduce this issue with simpler code : 
 
fn main() {
    let mut vector = vec!(1u, 2u);
    for &x in vector.iter() {
        let cap = vector.capacity();
        println!("Capacity was: {}", cap);
        vector.grow(cap, &0u); // be sure to cause reallocation
        *vector.get_mut(1u) = 5u;
        println!("Value: {}", x);
    }
}
 
It outputs : 
 
Capacity was: 4
Value: 1
Capacity was: 8
Value: 2
 
I'm modifying the vector content and reallocating, causing the underlying slice to refer to unallocated memory (vector.iter() is in fact vector.as_slice().iter()).
 
It looks like a recent change, it doesn't compile on rust 0.11 due to double borrow.
