Export data to Excel in WPF
Syncfusion Excel (XlsIO) library is a .NET Excel library used to create, read, and edit Excel documents. Using this library, you can import or export data between a worksheet and a DataTable in C# and VB.NET.
Syncfusion Excel (XlsIO) library supports exporting data from a worksheet to data tables and CLR objects, including DataTable and DynamicObjects. Exporting a DataTable to an Excel worksheet can be achieved through ImportDataTable only after the DataTable is filled with data.
Steps to export DataTable to an Excel file programmatically:
Step 1: Create a new C# WPF application project.
Create a new C# WPF application.
Step 2: Install the Syncfusion.XlsIO.Wpf NuGet package as a reference to your WPF applications from NuGet.org.
Install the NuGet package.
Step 3: Include the following namespaces in the Program.cs file.
C#
using Syncfusion.XlsIO; using System; using System.Data;
VB.NET
Imports Syncfusion.XlsIO Imports System Imports System.Data
Step 4: Add the following code snippet in the button click event to export the DataTable to an Excel file.
C#
//Create an instance of ExcelEngine
using (ExcelEngine excelEngine = new ExcelEngine())
{
// Initialize Application
IApplication application = excelEngine.Excel;
// Set the default application version as Excel 2016
application.DefaultVersion = ExcelVersion.Excel2016;
// Create a new workbook
IWorkbook workbook = application.Workbooks.Create(1);
// Access the first worksheet from the workbook instance
IWorksheet worksheet = workbook.Worksheets[0];
// Exporting DataTable to worksheet
DataTable dataTable = GetDataTable();
worksheet.ImportDataTable(dataTable, true, 1, 1);
worksheet.UsedRange.AutofitColumns();
// Save the workbook to disk in xlsx format
workbook.SaveAs("Output.xlsx");
}
VB.NET
'Create an instance of ExcelEngine
Using excelEngine As ExcelEngine = New ExcelEngine()
'Initialize Application
Dim application As IApplication = excelEngine.Excel
'Set the default application version as Excel 2016
application.DefaultVersion = ExcelVersion.Excel2016
'Create a new workbook
Dim workbook As IWorkbook = application.Workbooks.Create(1)
'Access the first worksheet from the workbook instance
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Exporting DataTable to worksheet
Dim dataTable As DataTable = GetDataTable()
worksheet.ImportDataTable(dataTable, True, 1, 1)
worksheet.UsedRange.AutofitColumns()
'Save the workbook to disk in xlsx format
workbook.SaveAs("Output.xlsx")
End Using
Step 5: Load the DataTable using the following simple method.
C#
private DataTable GetDataTable()
{
//Create a DataTable with four columns
DataTable table = new DataTable();
table.Columns.Add("Dosage", typeof(int));
table.Columns.Add("Drug", typeof(string));
table.Columns.Add("Patient", typeof(string));
table.Columns.Add("Date", typeof(DateTime));
//Add five DataRows
table.Rows.Add(25, "Indocin", "David", DateTime.Now);
table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);
table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);
table.Rows.Add(21, "Combivent", "Janet", DateTime.Now);
table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);
return table;
}
VB.NET
Private Function GetDataTable() As DataTable
'Create a DataTable with four columns
Dim table As DataTable = New DataTable
table.Columns.Add("Dosage", GetType(System.Int32))
table.Columns.Add("Drug", GetType(System.String))
table.Columns.Add("Patient", GetType(System.String))
table.Columns.Add("Date", GetType(DateTime))
'Add five DataRows
table.Rows.Add(25, "Indocin", "David", DateTime.Now)
table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now)
table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now)
table.Rows.Add(21, "Combivent", "Janet", DateTime.Now)
table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now)
Return table
End Function
