There is no one particular right way to do this. Like PIEBALD said, you'll have to create your own. Shouldn't be the tough. You'll need to have a way to store locally on the client machine the different connections, and other pertinent information needed for the connections.

Not sure if you can. It might be easier just to do your own

If it's even possible, the user would need to have Visual Studio installed to use your program.

Or will something like this help?
System.IO.FileInfo f = new System.IO.FileInfo ( "\\xt.udl" ) ;
f.OpenWrite().Close() ;
System.Diagnostics.Process p = System.Diagnostics.Process.Start ( "\\xt.udl" ) ;
p.WaitForExit() ;
System.Console.Write ( f.OpenText().ReadToEnd() ) ;

Does this[^] article help?

Yes, that is possible. Use the FileStream class to open the file, and use the Position property do decide where to read.
You will be reading bytes, of course, not characters.

I don't understand this, when I serialized my original index as 26 seperate hashtables, the index was only 1gig.
But just doing test runs with BinaryWriting and I shooting over 10gig easily on the same data.
Am I missing something here?

How are you serialising the data?

hi there,
i m reading a binary but it takes so long time to read, here is the codes
FileStream fs = new FileStream(@"D:\art1.bar", FileMode.Open);
BinaryReader br = new BinaryReader(fs);
string chk = "";
for (int a = 0; a < 4; a++)
{
chk += br.ReadChar().ToString();
}
int version = br.ReadInt32();
int unknown = br.ReadInt32();
byte[] uselessbytes = br.ReadBytes(264);
int unknown1 = br.ReadInt32();
int tnums = br.ReadInt32();
long dir = br.ReadInt64();
byte[] byts = br.ReadBytes(tnums);
br.BaseStream.Position = dir;
int dirnamelength = br.ReadInt32();
dirnamelength *= 2;
string dirname = "";
for (int a = 0; a < dirnamelength; a++)
{
dirname += br.ReadChar().ToString();
}
dirname = dirname.Replace("\0", "");
dirname = dirname.Replace("\\", "");
dirname = dirname.Replace(" ", "");
int numofFilesindir = br.ReadInt32();
for (int a = 0; a < numofFilesindir; a++)
{
dataGridView1.Rows.Add();
dataGridView1[1, a].Value = br.ReadInt32();
dataGridView1[2, a].Value = br.ReadInt32();
br.BaseStream.Position += 20;
int filelength = br.ReadInt32();
filelength *= 2;
string filename = "";
for (int b = 0; b < filelength; b++)
{
filename += br.ReadChar();
}
filename = filename.Replace("\0", "");
filename = filename.Trim();
filename.Remove(filename.Length - 3);
dataGridView1[0, a].Value = filename;
}
br.Close();
fs.Close();
it taking 15 seconds to read about 7000 files(i.e numofFilesindir = 7000)
i wanna know how can i reduce time or any alternative way that read fast

One reason is that you are concatening strings, this can become horribly slow inside loops, since each time a new string instance has to be created.
Use a StringBuilder instead and replace += with its Append method.
Also, you're reading the file byte by byte, why don't you read in all bytes at once an then convert the byte array to a string using the Encoding class?

ok i ll use string builder, and tell you the result

i cannot read in my format, its a file format of a game, thats why i have to read like that

7,000 files for a game?? A little excessive, don't you think?

its a archive file where about 7000 files stored, and there are about 8 or 9 more files like that have lots of files stored
i think you never edit any game...

i tried it too but no benefit

That's equivalent to:
object temp1 = (object)br.ReadChar();
string temp2 = fileName.ToString() + temp1.ToString();
fileName = temp2;
That means that you create three new objects for every single character that you read. If the filenames are 20 characters by average, that comes to 420000 objects for reading 7000 files.
Use the ReadChars method to read several characters from the stream.
xmen_xwk wrote: filename.Remove(filename.Length - 3);
That doesn't accomplish anything. The Remove method returns the new string, so you have to take care of the return value, just as you do with the Replace and Trim methods.

but if i use replace then it replace all the "//" from string , i just want to remove this from last of string, not in all
Guffa wrote: Use the ReadChars method to read several characters from the stream
yeah i used that but its just return "System.Char[]" something like that

That's just it. Your calling the Remove method, but completely ignoring the return from it. You can reomve the line completely from your code and nothing changes. It has to be:
filename = filename.Remove(something...);
