函数原型为:FILE *fopen(const char *filename, const char *mode); fopen(文件路径,文件使用方式); fopen函数打开filename指定的文件,返回一个指向FILE类型的指针,无论使用哪种方式,当打开文件时出现了错误,fopen函数都将返回NULL 常见的文件使用方式: "r"---以只读的方式打开文件(该文件必须已经存在,若文件不...
__BASE_FILE__ Defined to a string that contains the name of the main input file passed to Clang. __FILE_NAME__ Clang-specific extension that functions similar to__FILE__but only renders the last path component (the filename) instead of an invocation dependent full path to that file. _...

Off the Request object, you have the FilePath property, which you can then pass to a Path object to get just the filename part: Code: String MyPath = this.Request.FilePath; String Myfilename = Path.GetFileNameWithoutExtension(MyPath); You'll need to reference the System.IO namespace...

用C语言编写程序时,编写的内容被存储在文本文件中,该文件被称为源代码文件(source code file)。大部分C系统,包括之前提到的,都要求文件名以.c结尾(如,wordcount.c和budget.c)。在文件名中,点号(.)前面的部分称为基本名(basename),点号后面的部分称为扩展名(extension)。因此,budget是基本名,c是扩展名。基本名...
