你是想读取游戏进程吧 这个问题刚开始也 让我郁闷了很久 其实很多 游戏对读取内存做了特殊处理 常规的 调用api打开进程 读取内存 无效可以尝试 用token 直接调用就ok了 返回true说明调用成功下面是详细代码 Public Class ToKen

用.ini文件来存储。比如内容是:[UserInfo]UserName=admin读取方式:charachUserName[20];GetPrivateProfileString("UserInfo","UserName",NULL,achUserName,20,"c:\\userInfo.ini");
使用FileStream读写文件
文件头:
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
读文件核心代码:
byte[] byData = new byte[100];
char[] charData = new char[1000];
try
{
FileStream sFile = new FileStream("文件路径",FileMode.Open);
sFile.Seek(55, SeekOrigin.Begin);
sFile.Read(byData, 0, 100); //第一个参数是被传进来的字节数组,用以接受FileStream对象中的数据,第2个参数是字节数组中开始写入数据的位置,它通常是0,表示从数组的开端文件中向数组写数据,最后一个参数规定从文件读多少字符.
}
catch (IOException e)
{
Console.WriteLine("An IO exception has been thrown!");
Console.WriteLine(e.ToString());
Console.ReadLine();
return;
}
Decoder d = Encoding.UTF8.GetDecoder();
d.GetChars(byData, 0, byData.Length, charData, 0);
Console.WriteLine(charData);
Console.ReadLine();
写文件核心代码:
FileStream fs = new FileStream(文件路径,FileMode.Create);
//获得字节数组
byte [] data =new UTF8Encoding().GetBytes(String);
//开始写入
fs.Write(data,0,data.Length);
//清空缓冲区、关闭流
fs.Flush();
fs.Close();
2、使用StreamReader和StreamWriter
文件头:
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
StreamReader读取文件:
StreamReader objReader = new StreamReader(文件路径);
string sLine="";
ArrayList LineList = new ArrayList();
while (sLine != null)
{
sLine = objReader.ReadLine();
if (sLine != null!sLine.Equals(""))
LineList.Add(sLine);
}
objReader.Close();
return LineList;
StreamWriter写文件:
FileStream fs = new FileStream(文件路径, FileMode.Create);
StreamWriter sw = new StreamWriter(fs);
//开始写入
sw.Write(String);
//清空缓冲区
sw.Flush();
//关闭流
sw.Close();
fs.Close();
===================================================================================
方式一:用FileStream
//实例化一个保存文件对话框
SaveFileDialog sf = new SaveFileDialog();
//设置文件保存类型
sf.Filter = "txt文件|*.txt|所有文件|*.*";
//如果用户没有输入扩展名,自动追加后缀
sf.AddExtension = true;
//设置标题
sf.Title = "写文件";
//如果用户点击了保存按钮
if(sf.ShowDialog()==DialogResult.OK)
{
//实例化一个文件流---与写入文件相关联
FileStream fs = new FileStream(sf.FileName,FileMode.Create);
//获得字节数组
byte [] data =new UTF8Encoding().GetBytes(this.textBox1.Text);
//开始写入
fs.Write(data,0,data.Length);
//清空缓冲区、关闭流
fs.Flush();
fs.Close();
}
方式二:用StreamWriter
//实例化一个保存文件对话框
SaveFileDialog sf = new SaveFileDialog();
//设置文件保存类型
sf.Filter = "txt文件|*.txt|所有文件|*.*";
//如果用户没有输入扩展名,自动追加后缀
sf.AddExtension = true;
//设置标题
sf.Title = "写文件";
//如果用户点击了保存按钮
if (sf.ShowDialog() == DialogResult.OK)
{
//实例化一个文件流---与写入文件相关联
FileStream fs = new FileStream(sf.FileName, FileMode.Create);
//实例化一个StreamWriter--与fs相关联
StreamWriter sw = new StreamWriter(fs);
//开始写入
sw.Write(this.textBox1.Text);
//清空缓冲区
sw.Flush();
//关闭流
sw.Close();
fs.Close();
}
string FileName = Guid.NewGuid().ToString() + ".txt"; //GUID生成唯一文件名
StringBuilder ckpw = new StringBuilder("\"凭证输出\", \"V800\", \"001\", \"东风随州专用汽车有限公司\"," + "\"F89自由项16\", \"F90审核日期:\"");
if (!FileIO.IsFolderExists(Server.MapPath("pzsc")))
FileIO.CreaterFolder(Server.MapPath(""), "");
string filePath = Server.MapPath("pzsc") + "\\" + FileName;
System.IO.StreamWriter sw = new System.IO.StreamWriter(filePath, false, Encoding.GetEncoding("GB2312"));//创建的时候需要指定编码格式,默认是UTF-8,中文显示乱码
sw.WriteLine(ckpw.ToString());
sw.Close();
方式三:用BinaryWriter
//实例化一个保存文件对话框
SaveFileDialog sf = new SaveFileDialog();
//设置文件保存类型
sf.Filter = "txt文件|*.txt|所有文件|*.*";
//如果用户没有输入扩展名,自动追加后缀
sf.AddExtension = true;
//设置标题
sf.Title = "写文件";
//如果用户点击了保存按钮
if (sf.ShowDialog() == DialogResult.OK)
{
//实例化一个文件流---与写入文件相关联
FileStream fs = new FileStream(sf.FileName, FileMode.Create);
//实例化BinaryWriter
BinaryWriter bw = new BinaryWriter(fs);
bw.Write(this.textBox1.Text);
//清空缓冲区
bw.Flush();
//关闭流
bw.Close();
fs.Close();
}
C#缓存流示例------用缓存流复制文件
C#文件处理操作必须先导入命名空间:using System.IO;
背景:使用VS2005、一个按钮、一个窗体、C#缓存流、把D:\KuGoo\爱得太多.wma复制到D:\并更名为love.wma,即:D:\love.wma
在按钮的Click事件中添加如下代码:
private void button1_Click(object sender, EventArgs e)
{
//创建两个文件流 一个是源文件相关,另一个是要写入的文件
FileStream fs = new FileStream(@"D:\KuGoo\爱得太多.wma",FileMode.Open);
FileStream fs2 = new FileStream(@"D:\love.wma",FileMode.Create);
//创建一个字节数组,作为两者之间的媒介
//好比两个人拿苹果,这个字节数组就好比一个篮子,一个人作死的把苹果送到篮子里面,
//而我就可以作死得拿苹果,通过这个媒介我们互不干扰,
//不需要互相等待【她往篮子里面放了苹果我才可以去拿】,提高了效率
byte[] data = new byte[1024];
//创建两个缓冲流,与两个文件流相关联
BufferedStream bs = new BufferedStream(fs);
BufferedStream bs2= new BufferedStream(fs2);
//fs作死的读,fs2作死的写,直到fs没有字节可读fs2就不写了
//好比,一个人作死的往篮子里面丢苹果,另一个人作死得往篮子里面拿苹果,直到篮子里面没有苹果拿了为止
//即--那个人没有苹果往篮子里面放了
while(fs.Read(data,0,data.Length)0)
{
fs2.Write(data,0,data.Length);
fs2.Flush();
}
//关闭流,好比两个人累了,都要休息 呵呵o(∩_∩)o...
fs.Close();
fs2.Close();
}
C#内存流示例-----用内存流来读取图片
C#文件处理操作必须先导入命名空间:using System.IO;
背景:一个窗体、一个pictureBox、一个lable[没有选择图片,lable的text为"图片未选择"],在pictureBox1的Click事件中添加如下代码:
private void pictureBox1_Click(object sender, EventArgs e)
{
//实例化一个打开文件对话框
OpenFileDialog op = new OpenFileDialog();
//设置文件的类型
op.Filter = "JPG图片|*.jpg|GIF图片|*.gif";
//如果用户点击了打开按钮、选择了正确的图片路径则进行如下操作:
if(op.ShowDialog()==DialogResult.OK)
{
//清空文本
this.label1.Text = "";
//实例化一个文件流
FileStream fs = new FileStream(op.FileName, FileMode.Open);
//把文件读取到字节数组
byte[] data = new byte[fs.Length];
fs.Read(data, 0, data.Length);
fs.Close();
//实例化一个内存流---把从文件流中读取的内容[字节数组]放到内存流中去
MemoryStream ms = new MemoryStream(data);
//设置图片框 pictureBox1中的图片
this.pictureBox1.Image = Image.FromStream(ms);
}
}
这说明你调用 API 传参存在问题。
首先有没有设置结构体内存对齐?
[StructLayout(LayoutKind.Sequential)] 加了吗?
COLORREF 不要用 Color 代替,用 int 代替
TCHAR cfFaceName[32] 定义为 Byte 数组也可以,带在传参前,必须初始化为 32 个长度
