Find the matching file in folder

Question

Hello 
I have a table (datagrid), which contains references .
e.g.
 AZ7854
 AE7415
 AP7871
 AX7125
 BH7607
I also have a folder named Reports that contains several excels files .
the names of Excel files are   like this.
AZ7854-report2013.xlsx
 report2014 - AE7415.xlsx
 12 months report - AP7871.xlsx
 Overview - AX7125.xlsx
 report - BH7607.xlsx
The code that I want to write should be able to recover for each name in Datagrid, the corresponding Excel file. the code must search for each name, the Excel file that contains the reference.
Once the file is found, I think I can do the rest.
Can you help me please ?

The DataGrid's ItemsSource property is set or bound to the "table".
You could cast the ItemsSource property to the type of your collection or DataView and then iterate through all the objects/rows. The following example should give you the idea:
//fill DataGrid with the data:
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("ref"));
dt.Rows.Add("AZ7854");
dt.Rows.Add("AE7415");
yourDataGrid.ItemsSource = dt.DefaultView;
//retrieve the data and find the files:
System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(@"c:\yourpath\Reports");
System.IO.FileInfo[] files = dir.GetFiles("*.xlsx");
DataView data = yourDataGrid.ItemsSource as DataView;
foreach (DataRowView row in data) {
string val = row["ref"].ToString();
System.IO.FileInfo file = files.FirstOrDefault(f => f.Name.Contains(val));
//do something with the file...
