sharepoint 2010 - Upload file with meta data and checkin to sharpoint folder using Client Object Model -

hi i'm trying upload file sharepoint 2010 using client api meta data , checkin file after i'm done. below code:

public void uploaddocument(sharepointfolder folder, string filename, boolean overwrite) {

var fileinfo = new fileinfo(filename); var targetlocation = string.format("{0}{1}{2}", folder.serverrelativeurl,     path.altdirectoryseparatorchar, fileinfo.name);  using (var fs = new filestream(filename, filemode.open)) {     spfile.savebinarydirect(mclientcontext, targetlocation, fs, overwrite); }  // doesn't work spfile newfile = mrootweb.getfilebyserverrelativeurl(targetlocation); mclientcontext.load(newfile); mclientcontext.executequery();  //check out make sure not create multiple versions newfile.checkout();  // use overwritecheckin type make sure not create multiple versions  newfile.checkin("test", checkintype.overwritecheckin); mclientcontext.load(newfile); mclientcontext.executequery();  //spfile uploadfile = mrootweb.getfilebyserverrelativeurl(targetlocation);  //uploadfile.checkout(); //uploadfile.checkin("some version comment i'd add", checkintype.overwritecheckin);  //mclientcontext.executequery(); 

}

i'm able upload file can't add meta data , file checked out. want add meta data , checkin file after i'm done.

my sharepointfolder class has serverrelativeurl of folder path upload to. appreciated.

you need credential before executequery(); , savebinarydirect();

for example:

mclientcontext.credentials = new networkcredential("loginid","loginpw", "logindomain");  spfile newfile = mrootweb.getfilebyserverrelativeurl(targetlocation); mclientcontext.load(newfile); mclientcontext.executequery();
