wpf display google sheet in csharp

You can display Google Sheet data in a WPF application using the Google Sheets API and the Google API Client Library for .NET.

Here are the steps to achieve this:

  1. Create a new WPF application in Visual Studio.

  2. Install the Google.Apis.Sheets.v4 NuGet package.

  3. Create a new project in the Google Cloud Console and enable the Google Sheets API.

  4. Create credentials for your application to access the Google Sheets API.

  5. Create a service object using the Google API Client Library and authenticate it using the credentials obtained in step 4.

main.cs
using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Sheets.v4;

// Load the credentials file and create the Credentials object
var credential = GoogleCredential.FromFile("client_secret.json")
    .CreateScoped(SheetsService.Scope.SpreadsheetsReadonly);

// Create the Sheets API service
var service = new SheetsService(new BaseClientService.Initializer()
{
    HttpClientInitializer = credential,
    ApplicationName = "Google Sheets API WPF Display"
});

  1. Call the Google Sheets API to retrieve the data from the Google Sheet.
main.cs
// Define the range to retrieve data from
string spreadsheetId = "YOUR_SPREADSHEET_ID";
string range = "Sheet1!A1:D10"; // Change this to the range you want to retrieve

// Retrieve the data from the sheet
var request = service.Spreadsheets.Values.Get(spreadsheetId, range);
var response = await request.ExecuteAsync();

// Get the values from the response
IList<IList<object>> values = response.Values;

// Bind the data to your WPF user interface
// ...

Note that the API call is asynchronous and you should use await to retrieve the data in a non-blocking way.

  1. Bind the retrieved data to your WPF user interface.

You can bind the data to a DataGrid control in WPF using an ItemsSource property.

<DataGrid x:Name="MyDataGrid" ItemsSource="{Binding MyData}" />

main.cs
// Bind the data to your WPF user interface
MyDataGrid.DataContext = new { MyData = values };

This should display the retrieved data from the Google Sheet in a DataGrid control in your WPF application.
