字符串拆分的问题????????

[Novelty]

CString m_str="filename1:a.txt\r\nfilename2:b.txt\r\nfilename3:c.txt\r\n"
希望根据字符串的规则拆分出以下的三个变量:
CString m_filename1="a.txt";
CString m_filename2="b.txt";
CString m_filename3="c.txt";

多用两个 java.util.StreamTokenizer 拆一下就好

[iamfancy]

错了，应该是StringTokenizer

[swordbroken]

int count = 0;
int len;
CString m_str = "filename1:a.txt\r\nfilename2:b.txt\r\nfilename3:c.txt\r\n";

CString filename[10];
int left = 0,right = 0;
for(int i = 0; i < m_str.GetLength(); i ++)
{
left = m_str.Find(':',right) + 1;
if(left < i)
break;
right = m_str.Find("\r",left);
len = right - left;
filename[count++] = m_str.Mid(left,len);
i = right;

}

写个例子给你：
/**
* Test.java
* @author Fancy
*/

import java.util.*;

public class Test {

public static void main(String[] args) {
String s = "filename1:a.txt\r\nfilename2:b.txt\r\nfilename3:c.txt\r\n";
StringTokenizer st = new StringTokenizer(s, "\r\n");
StringTokenizer sst;
String m_filename1 = null;
String m_filename2 = null;
String m_filename3 = null;
while (st.hasMoreTokens()) {
//String t = st.nextToken();
sst = new StringTokenizer(st.nextToken(), ":");
String t1 = sst.nextToken();
String t2 = sst.nextToken();
if (t1.equals("filename1")) {
m_filename1 = t2;
} else if (t1.equals("filename2")) {
m_filename2 = t2;
} else {
m_filename3 = t2;
}
}
System.out.println(m_filename1);
System.out.println(m_filename2);
System.out.println(m_filename3);
}

}

不好意思，写昏头了，写了一个 Java 的例子给你，在 C 里是用 strtok 函数的，在 string.h 里，这是 MSDN 上的一个例子

#include <string.h>
#include <stdio.h>

char string[] = "A string\tof ,,tokens\nand some more tokens";
char seps[] = " ,\t\n";
char *token;

void main( void )
{
printf( "%s\n\nTokens:\n", string );
/* Establish string and get the first token: */
token = strtok( string, seps );
while( token != NULL )
{
/* While there are tokens in "string" */
printf( " %s\n", token );
/* Get next token: */
token = strtok( NULL, seps );
}
}
