Random Password Generator in C#.NET

-

This blog is going to illustrate the Random Password Generator in the .NET Framework. The GeneratePassword method is used to generate a random password and is most commonly used for reset password and new or temporary password. It is a very easy to use method.

GeneratePassword() method will generate the password with specific length.

The following is a syntax for GeneratePassword method

public static string GeneratePassword (int length, int numberOfNonAlphanumericCharacters);

Length (int): The password length

numberOfNonAlphanumericCharacters (int): Minimum no. of alphanumeric characters.

The following is a code snippet to generate a random password. Here length and nonAlphaNumeric values are passed to Membership.GeneratePassword() method. And the result has been assigned to the password textbox.

using System.Web.Security;
 
private void GeneratePasswordButton_Click(object sender, EventArgs e)
{
    passwordTextBox.Text =  Membership.GeneratePassword(int.Parse(lengthTextBox.Text), int.Parse(nonAlphaNumTextBox.Text));
}

The following is an output of the above code. The password is generated based on the length and number of alphanumeric characters.

I hope this helps you. Keep coding.

    The System.Web namespace, which includes the System.Web.Security.Membership.GeneratePassword(int length, int numberOfNonAlphanumericCharacters) method referenced in this article, is unsupported in .NET Core & .NET 5+.

    Thank you for your comment and bringing up an important point. You're absolutely right that the System.Web namespace, including the System.Web.Security.Membership.GeneratePassword method, is not supported in .NET Core and .NET 5+.

    You can use the RNGCryptoServiceProvider class to generate a random sequence of characters that can be combined to form a secure password

This blog is going to explain what is SignalR and how to implement it in ASP.NET Core. SignalR is a real time application framework for ASP.NET Core. Using SignalR you can provide updated information without refreshing the page, for example poll results, game score, chat etc. Let's see how to achieve it in ASP.NET Core MVC. Step 1: First step I added the SignalR client library. To add a SignalR client library, Right click on the project in Solution Explorer and Add -> Client-Side Library. Select the provider as unpkg as shown in the image below. Enter the latest version of SignalR into the library. And selected signalr.js and signalr.min.js files. Finally clicked the install button to install the client library. Step 2: At this step I have created a VoteHub.cs class inside the Hubs folder(create a new folder called Hubs). This class inherits from the Hub class which is a base class of SignalR hub. The SendMessage method will be called by the connected client.

Using Query Strings for Request Culture and Simplifying Localization with IStringLocalizer Interface Let’s see how to implement Localization in ASP.NET Core MVC. In the first example, I am going to use the IStringLocalizer Interface in the controller to implement Localization. Additionally, when the user passes the desired language through the query string, it will display content in that language. First, let’s configure the settings in the program.cs file. builder.Services.AddLocalization(options => options.ResourcesPath = "Resources");  The AddLocalization method adds the localization service to the service container. I have added the supported cultures here. I have added two cultures: en for English and nl for Dutch. In the RequestCultureProviders , I have included QueryStringRequestCultureProvider() . This allows the system to determine the culture information from the query string. UseRequestLocalization initializes a RequestLocalizationOptions objec
