I have a slaesforce webservice (generated from WSDL) having method UpdateStatus(data AS myObjects) as WSResponse.
On checking myObjects

public partial class myObject {
        
        private string statusField;
        
        private string strIdField;
        
        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
        public string status {
            get {
                return this.statusField;
            }
            set {
                this.statusField = value;
            }
        }
        
        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
        public string strId {
            get {
                return this.strIdField;
            }
            set {
                this.strIdField = value;
            }
        }
    }

Now I want to know how can I call this method in C# and pass parameters to this myObjects? 

I am following the steps in this  https://celedonpartners.com/blog/calling-a-custom-salesforce-rest-endpoint-using-c/ post to login to salesforce and call an API. Getting below error. Anybody could explain why is this error comming?

Hi All,
 Please let me know the steps what should be done for the below :
1) To send a Webservice Outbound call to another system.
2) Receive the response in XML Format
3) Parse the XML Response
4) Store the values in the system.
