在实际编程中,经常会用到Buffer,当string作为Buffer传值时需要注意的是 1, string的值的起始索引是1,千万记住! 2, 有时候需要先告诉系统去开辟出内存空间,用SetLength函数。 如下代码,示范了再Move、 WriteBuffer、 ReadBuffer时候的用法: unit Unit3; interface uses Windows, Messages, SysUtils, Variants, Class...
This example writes a string to a stream. #include <stdio.h> #define NUM_ALPHA 26 int main(void) { FILE * stream; int num; /* Do not forget that the '\0' char occupies one character */ static char buffer[NUM_ALPHA + 1] = "abcdefghijklmnopqrstuvwxyz"; if ((stream = fopen(...

然后,您可以一次读取一部分文件内容并将其写入到输出流。 InputStream fileInputStream =newFileInputStream("path/to/file"); OutputStream outputStream= ...;//假设这是您的输出流byte[] buffer =newbyte[1024];//缓冲区大小,可以根据需要调整intbytesRead;while((bytesRead = fileInputStream.read(buffer))...
// Write the original file data.if(fileStream.Length ==0) { tempString = lastRecordText + recordNumber.ToString(); fileStream.Write(uniEncoding.GetBytes(tempString),0, uniEncoding.GetByteCount(tempString)); } 備註 這個方法會覆寫Write。
