VS2010 内存错误0xC0000005: 读取位置 0x00000b00 时发生访问冲突

StrNot(char* inchar, char* outchar)
	{
		char str2[256];  	
		memset(str2,0,256);
		memset(outchar,0,256);
		//char str[] = "0123456789ABCDE";  	
		char ch[] = {'0','1','2','3','4','5','6','7', '8','9','A','B','C','D','E','F'};  
		for (int i=0; i <strlen(inchar); i++)  	
		{  		
			if ('0' <=inchar[i] && inchar[i] <='9')  			
			{
				str2[i] = ch[15-(inchar[i]-'0')]; 
			}
			else if ('A' <=inchar[i] && inchar[i] <='F')  		
			{
				str2[i] = ch[('F'-inchar[i])];  
			}
			else  
			{
				str2[i] = inchar[i];  	
			}
			//		str2[i] = 0;  
			//	 	strcat(outchar,(const char*)str2[i]);
			//	str2[i] = 0;  
		} 
		TRACE("%s\n", str2); 
		memcpy(outchar,str2,strlen((const char*)str2));
		return 0;
	}

代码如上，执行完后就会出现 ：0xC0000005: 读取位置 0x00000b00 时发生访问冲突，请教高手！

这里memset(outchar,0,256); 这个操作outchar正确？outchar的字节数是256 ？

注意内存，检查内存边界
