vb.net读取内存 vbnet读取文件内容

IT技术解压

vb.net尝试读取或写入受保护的内存 。这通常指示其他内存已损坏这说明vb.net读取内存你调用 API 传参存在问题 。
首先有没有设置结构体内存对齐vb.net读取内存？
[StructLayout(LayoutKind.Sequential)]加了吗？
COLORREF 不要用 Color 代替vb.net读取内存 ， 用 int 代替
TCHAR cfFaceName[32] 定义为 Byte 数组也可以vb.net读取内存，带在传参前vb.net读取内存，必须初始化为 32 个长度
vb.net 读取内存失败 求高手解答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
#Region "常数及结构声明"
Private Const SE_PRIVILEGE_ENABLED As Int32 = 2

如何用vb.net2003读写内存使用FileStream读写文件
文件头：
using System;
【vb.net读取内存 vbnet读取文件内容】using System.Collections.Generic;
using System.Text;
using System.IO;
读文件核心代码：
byte[] byData = https://www.04ip.com/post/new byte[100];
char[] charData = https://www.04ip.com/post/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);
