.NET(C#) 读取Resource资源文件的方法

1、嵌入的资源(Embedded Resource)

在VS(Microsoft Visual Studio)中将文件的生成操作设置 "嵌入的资源" 的读取方法，代码如下，

using (Stream stream = Assembly.GetExecutingAs().GetManifestResourceStream("PDF2PPT.Aspose.Total.lic"))
{
    string content = new StreamReader(stream).ReadToEnd();
}

2、资源(Resource)

在VS(Microsoft Visual Studio)中将文件的生成操作设置 "Resource" 的读取方法，代码如下，

Stream stream = null;
ResourceManager rm = new ResourceManager("PDF2PPT.g",typeof(Form1).Assembly);
ResourceSet rs = rm.GetResourceSet(new System.Globalization.CultureInfo("en"), true, true);
foreach (DictionaryEntry item in rs)
{
    if (item.Key.ToString() == fullname)
        stream = item.Value as Stream;
}
using (stream)
{
    string content = new StreamReader(stream).ReadToEnd();
}

3、.Resx资源文件

直接添加文件到.Resx资源文件中，在运行时使用Resource Manager读取，代码如下，

1）读取内容

string sTemplate = string.Empty;
Assembly assembly = Assembly.GetExecutingAssembly();
string resourceName = assembly.GetName().Name.ToString() + ".Resources.PageTemplate.html";
using (Stream stream = assembly.GetManifestResourceStream(resourceName))
{
   using (StreamReader sr = new StreamReader(stream))
   {
      sTemplate = sr.ReadToEnd();
   }
}

2）复制文件

string sDb = AppDomain.CurrentDomain.BaseDirectory + "rec.db";
if (!File.Exists(sDb))
{
    Assembly assembly = Assembly.GetExecutingAssembly();
    string resourceName = assembly.GetName().Name.ToString() + ".Resources.rec.db";
    using (Stream stream = assembly.GetManifestResourceStream(resourceName))
    {
        byte[] buffer = new byte[stream.Length];
        stream.Read(buffer, 0, buffer.Length);
        stream.Seek(0, SeekOrigin.Begin);
        using (FileStream fs = new FileStream(sDb, FileMode.Create))
            fs.Write(buffer, 0, buffer.Length);
    }
    Console.WriteLine($"db文件：{sDb}，不存在，已自动复制");
}

3）获取资源中的图像文件

Properties.Resources res = new Properties.Resources();PropertyInfo[] properInfo = res.GetType().GetProperties(BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Instance);foreach (PropertyInfo item in properInfo){    // 获取指定文件名格式的图片    if (item.Name.Contains("img_"))    {        Bitmap b = (Bitmap)Resources.ResourceManager.GetObject(item.Name, Properties.Resources.Culture);        using (MemoryStream stream = new MemoryStream())        {            b.Save(stream, ImageFormat.Jpeg);            byte[] data = new byte[stream.Length];            stream.Seek(0, SeekOrigin.Begin);            stream.Read(data, 0, Convert.ToInt32(stream.Length));            // do someting..        }    }}

4）获取资源中的字符串

string sVal = Resources.ResourceManager.GetObject(item.Name);
