soap client return cannot destabilize the response body netcore

Question

I have a dotnet app that consumes a SOAP service, the problem is when I call the service immediately return an exception said cant read the resulting body.

I tried to call the service through SOAP-UI, it worked very well.

below is the code was written to use the SOAP client.

        var request = new testRequest
        {
            moduleC = model.ModuleC.ToString(),
            moduleT = model.ModuleT.ToString(),
            Number = model.Number.ToString(),
        };
        var response = GetSoapResponse<TestRequest, TestResponse>((p) =>
        {
            var result = _client.TestMethod(request);
            return result;
        }, request);


private TResult GetSoapResponse<TParameters, TResult>(Func<TParameters, TResult> callback, TParameters parameters)
    {
        using (new OperationContextScope(_client.InnerChannel))
        {
            SetCredentials();
            var result = callback.Invoke(parameters);
            return result;
        }
    }

protected void SetCredentials() => OperationContext.Current.OutgoingMessageHeaders.Add(
                new UDBSecurityHeader(
                    Options.Username,
                    Options.Password));

And this is the code was generated from VS for the client :

    }

            this.RaisePropertyChanged("sequenceExceptionSpecified");
        }
    }

    public string status {
        get {
            return this.statusField;
        }
        set {
            this.statusField = value;
            this.RaisePropertyChanged("status");
        }
    }

        if ((propertyChanged != null)) {
            propertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
        }
    }
}

The expected XML response must be as the following:

<tns:TestResponse xmlns:tns="http://www.sampple.com/test">
     <tns:data>
        <tns:permitSequence>0.0</tns:permitSequence>
        <tns:sequenceException>0.0</tns:sequenceException>
        <tns:status>0</tns:status>
     </tns:data>
     <tns:statusCode>200</tns:statusCode>
     <tns:errors/>
     <tns:isSucceed>true</tns:isSucceed>

Answer 1

the data type that are return from the service are not allowed to mapped to the response for example if you have declared in response will return long and you are return decimal it couldn't be serialised from the response

private long permitSequenceField;

private long sequenceExceptionField;

the permitSequenceField and sequenceExceptionField are long you cant receive them as any another date type in xmlserializer

hope this solve your problem .
