RestClient - how to add SSL

Question

User-1852975005 posted

Hi, I have the below code;

I am new to this and I dont now if I am going about this in the right way at all.

The line - 

Client.RemoteCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true;

Gives the below error.

Severity	Code	Description	Project	File	Line	Suppression State
Error	CS0136	A local or parameter named 'sender' cannot be declared in this scope because that name is used in an enclosing local scope to define a local or parameter	restClient_0	C:\Users\Administrator\Desktop\VP-O\VP-0-REST-Client-master\VP-0-REST-Client-master\restClient_0\Form1.cs	27	Active

A dum question what is Sender and what is it asking for?

private void cmdGO_Click(object sender, EventArgs e)

        {

 

            var Client = new RestClient("https://xx.xx.xx.xx.:8443/xxxx/xxxxxx/work/");

 

            Client.RemoteCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true;

 

            var request = new RestRequest();

 

            request.AddHeader("authorization", "Basic xxxxxxxxxxxxxxxxxx");

 

            //Execute Request

            IRestResponse response = Client.Execute(request);

 

            txtResponse.Text = response.Content;

 

        }

Thanks,

Hi,

Use (request, certificate, chain, sslPolicyErrors) or whatever. "sender" is already an argument for cmdGO_Click. Not 100% sure. You could check the object type. I would expect this to be the object that triggers the validation (here likely the RestRequest in case you want to use it).

Even if you have to bypass validation errors, you could to still do some checks rather than accepting it unconditionally...

This is kind of a silky restriction in c# (they thought it would reduce bugs). Even in a new scope you can not use a variable name that exists in the outer scope. That just means you need to rename one of you sender varaiable.
