Explanation:
@page "/import-data"
: This directive makes this Blazor component accessible at the /import-data
URL.@using
Directives: These import necessary namespaces for configuration, Azure Blob Storage interaction, and your chosen SQL connector (in this case, MySqlConnector
for MySQL).@inject IConfiguration Configuration
: This injects the Blazor application's configuration, allowing you to access settings defined in appsettings.json
or Azure App Configuration.<h1>Import Data from Azure Blob Storage to SQL</h1>
.<p>
to display the importMessage
.<button>
that triggers the ImportSpreadsheetData
method when clicked. The button is disabled while the import is in progress.@code
Block: This section contains the C# logic for the component.importMessage
: A string variable to hold the status message of the import process.ImportSpreadsheetData()
(async Task): This asynchronous method handles the data import process.importMessage
to "Importing data..." and calls StateHasChanged()
to update the UI.try...catch...finally
): Encloses the import logic in a try...catch
block to handle potential errors and a finally
block to ensure the UI is updated.appsettings.json
or Azure App Configuration.BlobServiceClient
, BlobContainerClient
, and BlobClient
objects to interact with your Azure Blob Storage.StreamReader
to read the stream line by line.appsettings.json
or Azure App Configuration. The key here is ConnectionStrings:Forest404DB
.MySqlConnection
(or your chosen SQL connection object) using the connection string.CREATE TABLE IF NOT EXISTS
statement for the forest404
table with the specified columns and data types.MySqlCommand
object and executes the query.INSERT INTO
statement with parameterized placeholders (@business_url
, etc.) to prevent SQL injection.MySqlCommand
for the INSERT
statement for each data row.AddWithValue()
.INSERT
command asynchronously.rowCount
.importMessage
with the number of rows imported.importMessage
with the error message and logs the error to the console.StateHasChanged()
(in finally
): Forces Blazor to re-render the component, updating the UI with the final importMessage
.Azure Configuration Steps:
appsettings.json
: Add the following configuration (replace the placeholder values):
{ "AzureBlobStorage": { "ConnectionString": "YOUR_STORAGE_ACCOUNT_CONNECTION_STRING", "ContainerName": "data-import", "BlobName": "spreadsheet_data.csv" }, "ConnectionStrings": { "Forest404DB": "YOUR_MYSQL_CONNECTION_STRING" }, // ... other settings}
Azure App Configuration (Optional but Recommended for Production): Instead of appsettings.json
, you can store these sensitive configuration values in Azure App Configuration and configure your Blazor application to use it. This is a more secure way to manage configuration in production.

.xlsx
), you would need to incorporate a library like EPPlus
.async
and await
for non-blocking operations, which is good practice for Blazor applications to maintain responsiveness.@inject IConfiguration
is a good example of dependency injection in Blazor.This comprehensive example provides a solid foundation for importing data from Azure Blob Storage into a SQL database using C# and Blazor on Azure. Remember to adapt the configuration and data processing logic to your specific needs.
