我正在尝试使用CSHARPCODEPROVIDER来编译下面的代码。该文件已成功编译,但是当我单击生成的EXE文件时,我会收到一个错误(Windows正在搜索此问题的解决方案),什么也不会发生。
当我使用CSHARPCODEPROVIDER编译下面的代码时,我使用此代码行添加了MySql.Data.dll
作为嵌入式资源文件:
if (provider.Supports(GeneratorSupport.Resources))
cp.EmbeddedResources.Add("MySql.Data.dll");
该文件已成功嵌入(因为我注意到文件大小增加了)。
在下面的代码中,我尝试提取嵌入式dll文件并将其保存到System32,但是以下代码由于某种原因不起作用。
namespace ConsoleApplication1
{
class Program
{
public static void ExtractSaveResource(String filename, String location)
{
//Assembly assembly = Assembly.GetExecutingAssembly();
Assembly a = .Assembly.GetExecutingAssembly();
//Stream stream = assembly.GetManifestResourceStream("Installer.Properties.mydll.dll"); // or whatever
//string my_namespace = a.GetName().Name.ToString();
Stream resFilestream = a.GetManifestResourceStream(filename);
if (resFilestream != null)
{
BinaryReader br = new BinaryReader(resFilestream);
FileStream fs = new FileStream(location, FileMode.Create); // Say
BinaryWriter bw = new BinaryWriter(fs);
byte[] ba = new byte[resFilestream.Length];
resFilestream.Read(ba, 0, ba.Length);
bw.Write(ba);
br.Close();
bw.Close();
resFilestream.Close();
}
// this.Close();
}
static void Main(string[] args)
{
try
{
string systemDir = Environment.SystemDirectory;
ExtractSaveResource("MySql.Data.dll", systemDir);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
Console.ReadKey();
}
}
}
}
如何提取嵌入为资源的DLL文件并将其保存到System32?
我建议这样做更容易。我认为资源存在并且文件是可写的(如果我们谈论系统目录,这可能是一个问题)。
public void WriteResourceToFile(string resourceName, string fileName)
{
using(var resource = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName))
{
using(var file = new FileStream(fileName, FileMode.Create, FileAccess.Write))
{
resource.CopyTo(file);
}
}
}
我发现最简单的方法是使用Properties.Resources
和File
。这是我使用的代码(需要using System.IO
)...
对于二进制文件: File.WriteAllBytes(fileName, Properties.Resources.file);
用于文本文件: File.WriteAllText(fileName, Properties.Resources.file);
我一直在使用此(测试)方法:
outputdir:要复制资源的位置
Resourscelocation:名称空间( dirnames)
文件:资源限制中的文件列表,您要复制。
private static void ExtractEmbeddedResource(string outputDir, string resourceLocation, List<string> files)
{
foreach (string file in files)
{
using (System.IO.Stream stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceLocation + @"." + file))
{
using (System.IO.FileStream fileStream = new System.IO.FileStream(System.IO.Path.Combine(outputDir, file), System.IO.FileMode.Create))
{
for (int i = 0; i < stream.Length; i++)
{
fileStream.WriteByte((byte)stream.ReadByte());
}
fileStream.Close();
}
}
}
}
这很好!
public static void Extract(string nameSpace, string outDirectory, string internalFilePath, string resourceName)
{
//nameSpace = the namespace of your project, located right above your class' name;
//outDirectory = where the file will be extracted to;
//internalFilePath = the name of the folder inside visual studio which the files are in;
//resourceName = the name of the file;
Assembly assembly = Assembly.GetCallingAssembly();
using (Stream s = assembly.GetManifestResourceStream(nameSpace + "." + (internalFilePath == "" ? "" : internalFilePath + ".") + resourceName))
using (BinaryReader r = new BinaryReader(s))
using (FileStream fs = new FileStream(outDirectory + "\" + resourcename, FileMode.OpenOrCreate))
using (BinaryWriter w = new BinaryWriter(fs))
{
w.Write(r.ReadBytes((int)s.Length));
}
}
用法的示例:
public static void ExtractFile()
{
String local = Environment.CurrentDirectory; //gets current path to extract the files
Extract("Geral", local, "Arquivos", "bloquear_vbs.vbs");
}
如果仍然没有帮助,请尝试以下视频:https://www.youtube.com/watch?v=_61plvh2qpk
或使用扩展方法...
/// <summary>
/// Retrieves the specified [embedded] resource file and saves it to disk.
/// If only filename is provided then the file is saved to the default
/// directory, otherwise the full filepath will be used.
/// <para>
/// Note: if the embedded resource resides in a different assembly use that
/// assembly instance with this extension method.
/// </para>
/// </summary>
/// <example>
/// <code>
/// Assembly.GetExecutingAssembly().ExtractResource("Ng-setup.cmd");
/// OR
/// Assembly.GetExecutingAssembly().ExtractResource("Ng-setup.cmd", "C:tempMySetup.cmd");
/// </code>
/// </example>
/// <param name="assembly">The assembly.</param>
/// <param name="resourceName">Name of the resource.</param>
/// <param name="fileName">Name of the file.</param>
public static void ExtractResource(this Assembly assembly, string filename, string path=null)
{
//Construct the full path name for the output file
var outputFile = path ?? $@"{Directory.GetCurrentDirectory()}{filename}";
// If the project name contains dashes replace with underscores since
// namespaces do not permit dashes (underscores will be default to).
var resourceName = $"{assembly.GetName().Name.Replace("-","_")}.{filename}";
// Pull the fully qualified resource name from the provided assembly
using (var resource = assembly.GetManifestResourceStream(resourceName))
{
if (resource == null)
throw new FileNotFoundException($"Could not find [{resourceName}] in {assembly.FullName}!");
using (var file = new FileStream(outputFile, FileMode.Create, FileAccess.Write))
{
resource.CopyTo(file);
}
}
}
尝试将目标组件读取到MemoryStream
中,然后将其保存到FileStream
(请记住此代码未测试):
//Imports
using System;
using System.IO;
using System.Reflection;
Assembly assembly = Assembly.GetExecutingAssembly();
using (var target = assembly.GetManifestResourceStream("MySql.Data.dll"))
{
var size = target.CanSeek ? Convert.ToInt32(target.Length) : 0;
// read your target assembly into the MemoryStream
MemoryStream output = null;
using (output = new MemoryStream(size))
{
int len;
byte[] buffer = new byte[2048];
do
{
len = target.Read(buffer, 0, buffer.Length);
output.Write(buffer, 0, len);
}
while (len != 0);
}
// now save your MemoryStream to a flat file
using (var fs = File.OpenWrite(@"c:WindowsSystem32MySql.Data.dll"))
{
output.WriteTo(fs);
fs.Flush();
fs.Close();
}
}
string roamingfolder = System.IO.Directory.GetParent(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)).FullName
+ "\Roaming\hah";
string roamingfile = System.IO.Directory.GetParent(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)).FullName
+ "\Roaming\hah\image1.jpg";
Assembly asmbly = Assembly.GetExecutingAssembly();
const string NAME = "image_open2.Resources.Billi1609482658k220y8154.jpg";
if (File.Exists(roamingfile))
File.Delete(roamingfile);
if (!Directory.Exists(roamingfolder))
Directory.CreateDirectory(roamingfolder);
using (Stream stream = asmbly.GetManifestResourceStream(NAME))
{
using (FileStream fileStream = new FileStream(roamingfile, FileMode.Create))
{
for (int i = 0; i < stream.Length; i++)
{
fileStream.WriteByte((byte)stream.ReadByte());
}
fileStream.Close();
}
}
无需复杂化。首先,将汇编作为嵌入式资源。
private void ExtractAssembly(string dll)
{
if (!File.Exists(dll))
File.WriteAllBytes(dll, Resources.MyDLL);
}
这对我来说非常有用。
