Sending any value from one form to another form in WPF

Suppose I want to send some values from one form to another form in wpf application, then what to do?

In my application i have two window forms name as Test.xaml and Welcome.xaml like as follows:

Test.xaml

<Window x:Class="Login_WPF.Test" mlns=http://schemas.microsoft.com/winfx/2006/xaml/presentation
xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml
Title="Test" Height="300" Width="300">
<Grid>
   <Button Content="Submit" Height="23" HorizontalAlignment="Left" Margin="30,0,0,150" Name="Ok" VerticalAlignment="Bottom" Width="75" Click="Ok_Click" />
   <TextBox Height="23" HorizontalAlignment="Left" Margin="30,46,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" />
   <Label Content="Enter your name here" Height="28" HorizontalAlignment="Left" Margin="26,12,0,0" Name="label1" VerticalAlignment="Top" />
</Grid>
</Window>

Welcome.xaml:

<Window x:Class="Login_WPF.Welcome"
xmlns=http://schemas.microsoft.com/winfx/2006/xaml/presentation
xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml
Title="Welcome" Height="300" Width="350">
<Grid>
   <TextBlock Height="23" HorizontalAlignment="Left" Margin="10,10,0,0" x:Name="WelcomeHeading" Text="Welcome:" VerticalAlignment="Top" FontSize="17" FontStretch="ExtraCondensed"/>
   <TextBlock Height="23" HorizontalAlignment="Left" Margin="90,10,0,0" x:Name="TextBlockName" VerticalAlignment="Top" FontSize="15" FontStretch="ExtraCondensed" />
</Grid>
</Window>

My first page is Test.xaml. write the following lines of code on button's click event as follows:

Test.xaml.cs:

using System;
sing System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
namespace Login_WPF
{
   /// <summary>
   /// Interaction logic for Test.xaml
   /// </summary>

   public partial class Test : Window
   {
      public Test()
      {
         InitializeComponent();
      }

      private void Ok_Click(object sender, RoutedEventArgs e)
      {
         Welcome objWelcome = new Welcome();
         objWelcome.TextBlockName.Text = textBox1.Text;
         objWelcome.Show(); //Sending value from one form to another form.
         Close();
      }
   }
}

Output:
