Dim entitycnxstringbuilder new entityconnectionstringbuilder

A C# code snippet!

Dim entitycnxstringbuilder As New EntityConnectionStringBuilder

This line of code is creating a new instance of the EntityConnectionStringBuilder class, which is used to build a connection string for an Entity Framework (EF) database connection.

Here's a breakdown of the code:

• Dim is the keyword used to declare a variable in Visual Basic.NET (VB.NET).
• entitycnxstringbuilder is the name of the variable being declared.
• As New is used to create a new instance of the EntityConnectionStringBuilder class.
• EntityConnectionStringBuilder is the class being instantiated.

The EntityConnectionStringBuilder class is used to build a connection string that can be used to connect to a database using Entity Framework. The connection string is built by specifying various properties, such as the database provider, connection string, and other settings.

For example, you might use the EntityConnectionStringBuilder class to build a connection string like this:

Dim entitycnxstringbuilder As New EntityConnectionStringBuilder
entitycnxstringbuilder.Provider = "System.Data.SqlClient"
entitycnxstringbuilder.ProviderConnectionString = "Data Source=myserver;Initial Catalog=mydatabase;User ID=myusername;Password=mypassword;"
entitycnxstringbuilder.Metadata = "res://*/MyModel.csdl|res://*/MyModel.ssdl|res://*/MyModel.msl"
Dim connectionString As String = entitycnxstringbuilder.ToString()

This code creates a new EntityConnectionStringBuilder instance, sets various properties, and then converts the builder to a string using the ToString() method. The resulting connection string can be used to connect to a SQL Server database using Entity Framework.
