Made XML file from object collection witrh LINQ

Hi,

Last time i seem in the forum, he ask a question how to make XML file from the object collection or array with LINQ.Because of LINQ has a excellent support to XML.

Here Code snippet.

To this i just take simple example.

C#.NET


Private void MakeXMlFile()
{

Employee[] employees = new[] {
new Employee {FirstName = "Joe", LastName = "Rattz", Email="Test@hotmail.com",Phone="12345343"
},
new Employee {FirstName = "Ewan", LastName = "Buckingham",
Email="Test2@hotmail.com",Phone="122232345343"}};

XElement xBookParticipants =
new XElement("Employees",
employees.Select(p =>
new XElement("Employee",
new XElement("FirstName", p.FirstName),
new XElement("LastName", p.LastName),new XElement("Email",p.Email),
new XElement("Phone",p.Phone))));
Console.WriteLine(employees);

}


VB.NET

Class Employee
Public FirstName As String
Public LastName As String
Public Email As String
Public Phone As String
End Class


private sub MakeXML()

Dim employees As Employee() = New () {New Employee(), New Employee()}

Dim xBookParticipants As New XElement("Employees", employees.[Select](Function(p) New XElement("Employee", New XElement("FirstName", p.FirstName), New XElement("LastName", p.LastName), New XElement("Email", p.Email), New XElement("Phone", p.Phone))))
Console.WriteLine(employees)
Console.ReadLine()
End Sub

How to write Gridview data to XML file in .NET

Hi,

One my colleague asked me yesterday , how we could save the Grid View Data to XML File, just i think come to this point and share with you.

Just Read data from the Grid View to DataSet, then we need write that dataset ti XML file.

C#:

DataSet ds = new DataSet("TestDataset");
DataTable dt = new DataTable("TestDataTable");
dt.Columns.Add("Id", System.Type.GetType("System.String"));
ds.Tables.Add(dt);
//Add any number columns here
for (int count = 0; count < GridView1.Rows.Count; count++)
{
DataRow dr = dt.NewRow();
dr[0] = GridView1.Rows[count].Cells[0].Text;
//you can add values to all columns in datatable
dt.Rows.Add(dr);
}
ds.Tables[0].WriteXml("d:\\test2.xml");


VB.NET:

Dim ds As New DataSet("TestDataset")
Dim dt As New DataTable("TestDataTable")
dt.Columns.Add("Id", System.Type.[GetType]("System.String"))
ds.Tables.Add(dt)
'Add any number columns here
For count As Integer = 0 To GridView1.Rows.Count - 1
Dim dr As DataRow = dt.NewRow()
dr(0) = GridView1.Rows(count).Cells(0).Text
'you can add values to all columns in datatable
dt.Rows.Add(dr)
Next
ds.Tables(0).WriteXml("d:\test2.xml")


That's it

Search a types of file within the Directory with recursive in C#

Hi Guys,

Following code support to search types file with in the Directory including sub directories also.

public class FileSearch
{
ArrayList _extensions;
bool _recursive;
public ArrayList SearchExtensions
{
get { return _extensions; }
}
public bool Recursive
{
get { return _recursive; }
set { _recursive = value; }
}
public FileSearch()
{
_extensions = ArrayList.Synchronized(new ArrayList());
_recursive = true;
}
public FileInfo[] Search(string path)
{
DirectoryInfo root = new DirectoryInfo(path);
ArrayList subFiles = new ArrayList();
foreach (FileInfo file in root.GetFiles())
{
if (_extensions.Contains(file.Extension))
{
subFiles.Add(file);
}
}
if (_recursive)
{
foreach (DirectoryInfo directory in root.GetDirectories())
{
subFiles.AddRange(Search(directory.FullName));
}
}
return (FileInfo[])subFiles.ToArray(typeof(FileInfo));
}
}

How to Use:

FileSearch fileser = new FileSearch();
fileser.Recursive = true;
fileser.SearchExtensions.Add(".rar");
FileInfo[] dirRar = fileser.Search("D:\\test");

Create A Complete Grid with programmetrically in C#

Hi,

This code snippet to help build windows form grid Under the Windows Presentation Foundation with Winodws Host Object.and also it C# code.

Note:Before add this code you need add Windows Host Object WPF Windows under the any parent control, and also rename to windowsFormsHostDetail.

internal void WindowsFormGridInit()
