[refference]http://stackoverflow.com/questions/3395381/c-sharp-converting-a-string-containing-a-floating-point-to-an-integer

var
a =(int)Convert.ToDouble("1.2");

Note if you're using comma as a number separator in your operating system, you have to use IFormatProvider:

var a =(int)Convert.ToDouble("1.2",CultureInfo.InvariantCulture.NumberFormat);

Another way to accomplish this task:

var a =int.Parse("1.2".Split('.')[0]);

I found this solution to work for me when trying to access a file share on another computer.  It basically simulates doing a NET USE command where you can specify the credentials to use on the remote end.  The nice part is that you do not have to impersonate the user and it works across domains and workgroup computers.

First, declare these functions and types in your class.

using System.Reflection;
using System.Runtime.InteropServices;
using System.ComponentModel;

public class YourClass {
[DllImport("mpr.dll")]
private static extern int WNetAddConnection2A(ref NetResource pstNetRes, string psPassword, string psUsername, int piFlags);
[DllImport("mpr.dll")]
private static extern int WNetCancelConnection2A(string psName, int piFlags, int pfForce);

[StructLayout(LayoutKind.Sequential)]
private struct NetResource {
    public int iScope;
    public int iType;
    public int iDisplayType;
    public int iUsage;
    public string sLocalName;
    public string sRemoteName;
    public string sComment;
    public string sProvider;
}

private const int RESOURCETYPE_DISK = 0x1;

Then, add these two methods.
   
    private void LoginToShare(string serverName, string shareName, string user, string password) {
        string destinationDirectory = string.Format(@"\\{0}\{1}", serverName, shareName);

        NetResource nr = new NetResource();
        nr.iScope = 2;
        nr.iType = RESOURCETYPE_DISK;
        nr.iDisplayType = 3;
        nr.iUsage = 1;
        nr.sRemoteName = destinationDirectory;
        nr.sLocalName = null;

        int flags = 0;
        int rc = WNetAddConnection2A(ref nr, password, user, flags);

        if (rc != 0) throw new Win32Exception(rc);
    }

    private void LogoutFromShare(string serverName, string shareName) {
        string destinationDirectory = string.Format(@"\\{0}\{1}", serverName, shareName);
        int flags = 0;
        int rc = WNetCancelConnection2A(destinationDirectory, flags, Convert.ToInt32(false));
    }


In your code, call the LoginToShare with the server, share, user, and password needed.  Then simply use the standard \\server\share\path conventions for accessing files on remote computers.  Call the LogoutFromShare when you're done.

ajax 용 웹페이지 파싱할 때위처럼 구현하면 여러번 사이트 로딩 되는 현상을 방지 할 수 있다.

프로그램을 하다 보면 중복되면 안되는 GUID를 만들어야 할 경우가 생긴다.
C#즉 .netframework 에서는 GUID를 쉽게 생성 할 수 있도록 API를 제공해준다.

[msdn]

http://msdn.microsoft.com/en-us/library/system.guid.newguid.aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-1

     Guid g;
    g = Guid.NewGuid();
    Console.WriteLine(g);
    Console.WriteLine(Guid.NewGuid());

위소스는 msdn에서 발췌 했습니다.
