我有麻烦open()。它总是返回-1，我不知道代码出了什么问题。它一直在说：

r1: No such file or directory

Run Code Online (Sandbox Code Playgroud)

但是txt文件与C程序位于同一目录中。

#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <fcntl.h>

#define BUFFSIZE 256

char upper(char c);

int main(void){

    int fd1, read1, fd2, write2;
    char *buffer[BUFFSIZE];

    fd1 = open("minuscole.txt", O_RDONLY);
    if (fd1 < 0) { perror("r1"); exit(1); }
    read1 = read(fd1, buffer, BUFFSIZE);
    close(fd1);

    printf("%d", read1);
    if(fd2 = open("maiuscole.txt", O_WRONLY | O_CREAT | O_TRUNC, 0644) > 0){
        write2 = write(fd2, buffer, BUFFSIZE);
    }
    close(fd2);

    return 0;
}

我希望它创建一个名为：的文件，"maiuscole.txt" …

I've made a library and I've imported it adding a reference in the project and put using the namespace of my library, but when I'm trying to use a method it shows me an error. "The type or namespace name 'UploadFiles' does not exist in the namespace 'MyGoogleUDS'(are you missing an assembly reference?)"

Project:

using MyGoogleUDS;

error on this call:

MyGoogleUDS.UploadFiles("..\\" + asset.Name);

My library:

namespace MyGoogleUDS
{
    public class MyGoogleUDS
    {
        public static void UploadFiles(string path)
        {
            ...
        } …
