C# – First steps with C# and .NET – part 012 . – free-tutorials.org news free tutorials source code development scripts

In this tutorial, I will show you how to start using Google Cloud Platform with Visual Studio 2019 and C#.
The main goal is to create a Cloud Storage buckets.
First, create a console project into your Visual Studio 2019 I.D.E.

Open the cloud google.com dotnet webpage and use Try It Free option.
This allows you to use a free account with 300$ free option:

Make all settings for your account, add your account credit card, and a new project will create and named My First Project.
Into your Visual Studio 2019 open into main menu Tools – NuGet Package Manager – Package manager Console and use this command to install Google client library to access the Google Cloud Storage API:

Install-Package Google.Cloud.Storage.V1 -Version 3.1.0

1	Install-Package Google.Cloud.Storage.V1 -Version 3.1.0

Use the Set up a project button from the same webpage to set up your project.
This will show you a window with some information for your project and download the JSON file:

The JSON file can be found on this URL: https://console.cloud.google.com/apis/credentials?project=YOUR-PROJECT-ID.
If you want to create another JSON or set an authentication credential, see this webpage.
You need to have a billing account in order to use this example, see this webpage.
If not you will get this error:

The project to be billed is associated with an absent billing account. [403]
Errors [
	Message[The project to be billed is associated with an absent billing account.] Location[Authorization - header] Reason[accountDisabled] Domain[global]

The project to be billed is associated with an absent billing account. [403]

Errors [

Message[The project to be billed is associated with an absent billing account.] Location[Authorization - header] Reason[accountDisabled] Domain[global]

This information should be used in the following source code:

using System;
using System.Diagnostics;
using Google.Cloud.Storage.V1;

namespace Google_Cloud_001
{
    class StorageQuickstart
    {
        static void Main(string[] args)
        {
            // Your Google Cloud Platform project ID.
            string projectId = "YOUR-PROJECT-ID";
            //Authenticate to the service by using Service Account
            System.Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS","D:\\your_project.json");


            // Instantiates a client.
            using (StorageClient storageClient = StorageClient.Create())
            {
                // The name for the new bucket.
                string bucketName = projectId + "-test-bucket";
                try
                {
                    // Creates the new bucket.
                    storageClient.CreateBucket(projectId, bucketName);
                    Console.WriteLine($"Bucket {bucketName} created.");
                }
                catch (Google.GoogleApiException e)
                when (e.Error.Code == 409)
                {
                    // The bucket already exists.  That's fine.
                    Console.WriteLine(e.Error.Message);
                }
            }
        }
    }
}

using System;

using System.Diagnostics;

using Google.Cloud.Storage.V1;

namespace Google_Cloud_001

{

class StorageQuickstart

{

static void Main(string[] args)

{

// Your Google Cloud Platform project ID.

string projectId = "YOUR-PROJECT-ID";

//Authenticate to the service by using Service Account

System.Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS","D:\\your_project.json");

// Instantiates a client.

using (StorageClient storageClient = StorageClient.Create())

{

// The name for the new bucket.

string bucketName = projectId + "-test-bucket";

try

{

// Creates the new bucket.

storageClient.CreateBucket(projectId, bucketName);

Console.WriteLine($"Bucket {bucketName} created.");

}

catch (Google.GoogleApiException e)

when (e.Error.Code == 409)

{

// The bucket already exists. That's fine.

Console.WriteLine(e.Error.Message);

}

Build the project and run it, will work well:
