在 .net 中释放嵌入的资源

private static void ExtractResourceToFile(string resourceName, string filename)
{
    if (!System.IO.File.Exists(filename))
        using (System.IO.Stream s = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName))
        using (System.IO.FileStream fs = new System.IO.FileStream(filename, System.IO.FileMode.Create))
        {
            byte[] b = new byte[s.Length];
            s.Read(b, 0, b.Length);
            fs.Write(b, 0, b.Length);
        }
}

ExtractResourceToFile("MergeCell.Interop.Excel.dll", "Interop.Excel.dll");
ExtractResourceToFile("MergeCell.Office.dll", "Office.dll");    

VB.Net中资源的名称为：项目默认命名空间.资源文件名 
C#中则是：项目命名空间.资源文件所在文件夹名.资源文件名 
例:
[C# code]
Assembly assm = Assembly.GetExecutingAssembly();
istr = assm.GetManifestResourceStream("项目命名空间.资源文件所在文件夹名.资源文件名");
