To call a function and see the definition of any function data in .NET, you can follow these steps:

Step 1. Open Visual Studio and create a new console application project.
Step 2. In the Solution Explorer, right-click on the roject and select “Add” >; “Class”. Name the class “SampleClass”.
Step 3. In the SampleClass, create a public function called “SampleFunction” with some sample data, for example:

public void SampleFunction(int number1, int number2)
{
 int result = number1 + number2;
 Console.WriteLine($"The result of adding {number1} and {number2} is {result}");
}

Step 4. Save the class and go back to the main program file (usually Program.cs).
Step 5. In the Main function, instantiate an instance of the SampleClass and call the SampleFunction with some data:

static void Main(string[] args)
{
 SampleClass sampleObj = new SampleClass();
    sampleObj.SampleFunction(5, 7);
}

Step 6. Run the program and observe the output in the console window.
To see the definition of the SampleFunction or any other function, you can either hover your mouse over the function name in the code editor to see a summary of the function signature, or you can right-click on the function name and select “Go To Definition”. This will take you to the location in the code where the function is defined.

Now get the information with created function dbo.func_GetCurrentAssignedBillPayertbl(@ArticleId) using a select statement.Here @ArticleId is a parameter which return informations related to function.select * from dbo.func_GetCurrentAssignedBillPayertbl(33517) and if any one see the Definition of any Function Data then write as following-sp_helptext func_GetCurrentAssignedBillPayertbl.
