来自于reactos的C＃的C代码 [英] C code to C# from reactos

问题描述

我已经用C语言将源代码转换为C＃，但是有很多错误，我需要帮助：

I've converted a source code in C language to C# but there is a lot of errors, I need a help:

internal static VOID partstrlwr(string str)
{
    string c = str;
    while ( c && !_istspace ( c) && c != _T('='))
    {
        c = _totlower ( c);
        c++;
    }
}

推荐答案

转换的函数应该是这样的，也许是

The function converted should like this,maybe

internal static void partstrlwr(ref string str)
{
    CharEnumerator c = str.GetEnumerator();

    str = string.Empty;

    while (c.MoveNext())
    {
        if (!c.Current.Equals(' ') && !c.Current.Equals('='))
        {
            str += c.Current.ToString().ToLower();
        }
        else
        {
            str += c.Current.ToString();
        }
    }
}

我认为只需使用String.ToLower（）代替partstrlwr，因为这两者在C＃中没有区别。

I think just use "String.ToLower()" instead of the "partstrlwr",since no difference here beween this two in C#.

循环只检查三个条件都是真的：

1） c 不是null（C语言使用空终止字符串; C＃不; t）

2）无论_istspace函数做什么，倒置。因此，如果参数是空格，则返回true，那么循环不需要空格。

3） c 字符是不是等号。



循环中的代码看起来像垃圾。

转换 c 小写，所以'A'变为'a'等等。但是因为 c 是一个字符串，所以它的作用是任何人猜测

增加字符串 - 我不知道它会做什么...因为你从来没有用它作为指针...



你知道的地方（以及为什么）我不知道。

但就个人而言，我会把它放回去，假装我从未见过它......

The loop just checks the three conditions are all true:
1) c is not a null (the C language uses null terminated strings; C# doesn;t)
2) Whatever the _istspace function does, inverted. So if it returns "true" if the parameter is a space, then the loop wants it not a space.
3) The c character is not an equals sign.

The code in the loop itself looks like garbage.
Convert c to lower case, so 'A' becomes 'a' and so forth. But since c is a string, quite what it does to that is anybodies guess
Increment the string - and I have no idea what that will do...since you never use this as a pointer...

Quite where you got that (and why) I don't know.
But personally, I'd put it back and walk away pretending I'd never seen it...
