WCF and HTTPS, Error: There was no endpoint listening at, This is often caused by an incorrect address or SOAP action I'm trying to configure a WCF Service to work over HTTPS and I'm having a lot of issues.
In order to make your question clearer, it is necessary to provide the related code snippet in your project that cause the exception. According to the description of your calculator VB.NET project, I would like to provide you the comments as follows: 1. Suppose that there is a function that reads a file and formats the data from that file.
An error occurs in the Web Service call and the innermost exception holds the useful error information which in this case points at an invalid web.config key value related to the System.Net connection APIs.
Equals(Object) Determines whether the specified object is equal to the current object. (Inherited from Object): GetBaseException When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. Product key for microsoft office.

Inner Exception in C# with an Example
In this article, I am going to discuss the Inner Exception in C# with examples. Please read our previous article before proceeding to this article where we discussed how to create a Custom Exception in C# with examples. At the end of this article, you will understand what is Inner Exception and its need in C#.
What is Inner Exception in C#?
The Inner Exception in C# is a property of an exception class. When there is a series of exceptions, then the most current exception obtains the previous exception details in the InnerException property. In order words, we can say that the InnerException property returns the original exception that caused the current exception. If this is not clear at the moment, then don’t worry we will discuss this with examples.
Inner Exception Example in C#:
Let us say we have an exception inside a try block which is throwing DivideByZeroExceptionand the catch block catches that exception and then tries to write that exception it to a file. However, if the file path is not found, then the catch block is also going to throw FileNotFoundException.
Let’s say the outside try block catches this FileNotFoundException exception, but how about the actual DivideByZeroExceptionthat was thrown? Is it lost? No, the InnerException property of the Exception class contains the actual exception.
Example:
Let us understand the Inner Exception with an example. In order to see the inner exception, we have to make this program cause an exception to fail. To do that we have 3 options
Enter a Character instead of a number (Causes Format Exception)
Or Enter a very big number that an integer cannot hold (Causes Over Flow Exception)
Vb.net Innerexception Null
Or Enter Zero for Second Number (Causes Divide By Zero Exception)
Vb.net Innerexception 使い方
When you run the above program it will give us the following output.
Vb.net Throw New Exception Innerexception
