How to implement SAP Webservice in C#

Create WSDl file through web service URL and save it

open visual studion and add service reference

Code

For Serlization

public static string SerializeObject<T>(this T toSerialize)
{
    XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType());

    using (StringWriter textWriter = new StringWriter())
    {
        xmlSerializer.Serialize(textWriter, toSerialize);
        return textWriter.ToString();
    }
}

public static T DeSerializeObject<T>(this T toSerialize, string serializedData)
{
    XmlSerializer deserializer = new XmlSerializer(toSerialize.GetType());
    using (TextReader tr = new StringReader(serializedData))
    {
        T deserializedPerson = (T)deserializer.Deserialize(tr);
        return deserializedPerson;
    }
}

For Access The Sap API

public ZbapiMmoeWaterResponse GetWaterTankDetail(string vehicleno)
{
    ZbapiMmoeWater objWaterRequest = new ZbapiMmoeWater
    {
        Vehicleno = vehicleno
    };

    BasicHttpBinding binding = new BasicHttpBinding();
    binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
    binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
    EndpointAddress endpoint = new EndpointAddress(ConstantHelper.WaterTanlApiUrl);
    ZSESA_WATER_TANKER_interfaceClient client = new ZSESA_WATER_TANKER_interfaceClient(binding, endpoint);
    client.ClientCredentials.UserName.UserName = ConstantHelper.SapUserName;
    client.ClientCredentials.UserName.Password = ConstantHelper.SapPassword;

    ZbapiMmoeWaterResponse objWaterResponse = client.ZbapiMmoeWater(objWaterRequest);

    return objWaterResponse;
}

For WebApi Acode

public class WaterTankApiController : ApiController
{
    [Route("WaterTankApi/GetVehcileDetail/{VehcileNo}")]
    public string GetVehcileDetail(string VehcileNo)
    {
        var objWaterTank = (new WaterTankOperation()).GetVehcileDetail(VehcileNo);
        var ObjSerializer = new JavaScriptSerializer();
        string json = ObjSerializer.Serialize(objWaterTank);

        return json;
    }
}
