Here, I have used some free web services and consume it to show country, country code, currency and currency code of any country.
I have designed my form like the following screenshot:
![]()
And here is the HTML code for this.
- <body>
- <form id="form1" runat="server">
- <div style="margin-left:200px;border-style:solid; border-color:aqua; width:270px;height:300px;">
- <div>
- Country:
- </div>
- <div>
- <asp:DropDownList ID="ddl_country" runat="server" AutoPostBack="True" Height="21px" OnSelectedIndexChanged="ddl_country_SelectedIndexChanged" Width="250px"></asp:DropDownList>
- </div>
- <br />
- <div>
- Country Code
- </div>
- <div>
- <asp:TextBox runat="server" ID="txt_countrycode"></asp:TextBox>
- </div>
- <br />
- <div>
- Currency;
- </div>
- <div>
- <asp:TextBox runat="server" ID="txt_currency"></asp:TextBox>
- </div>
- <br />
- <div>
- CurrencyCode:
- </div>
- <div>
- <asp:TextBox runat="server" ID="txt_isd"></asp:TextBox>
- </div>
- </div>
- </form>
- </body>
Now in this project I am going to add the service Reference.
![]()
You can get the web service in this
link.
Now go to the webservice page and copy the link for
getcountry. Now add this link in web service reference.
![]()
Give an appropriate Namespace and search the link by clicking the GO button.
![]()
![]()
Then click ok.
Now here I am writing the code by using the namespace to get all country name and binding them in the dropdownlist.
- protected void Page_Load(object sender, EventArgs e)
- {
- if (!IsPostBack)
- {
- fillcountry();
- }
- }
- public void fillcountry()
- {
- myservice.countrySoapClient obj = new myservice.countrySoapClient();
- var country = obj.GetCountries();
- StringReader stream = null;
- XmlTextReader reader = null;
- DataSet ds = new DataSet();
- stream = new StringReader(country);
-
- reader = new XmlTextReader(stream);
- ds.ReadXml(reader);
- ddl_country.DataSource = ds;
- ddl_country.DataTextField = "Name";
- ddl_country.DataBind();
- }
Now it will bind all the countries to the dropdown list.
![]()
Now change the
AutoPostBack property to true.
![]()
And write to get the country code, currency, currency code, etc in ddl_country_SelectedIndexChanged. Here is the code.
- protected void ddl_country_SelectedIndexChanged(object sender, EventArgs e) {
- myservice.countrySoapClient obj = new myservice.countrySoapClient();
- string currency = obj.GetCurrencyByCountry(ddl_country.SelectedItem.Text);
- StringReader stream = null;
- XmlTextReader reader = null;
- DataSet ds = new DataSet();
- stream = new StringReader(currency);
- reader = new XmlTextReader(stream);
- ds.ReadXml(reader);
- txt_currency.Text = ds.Tables[0].Rows[0]["Currency"].ToString();
- txt_countrycode.Text = ds.Tables[0].Rows[0]["CountryCode"].ToString();
- txt_isd.Text = ds.Tables[0].Rows[0]["Currencycode"].ToString();
- }
Now run the project and choose any country from the DropDownList, you will get all the details.
![]()
Thus in this way we can consume web service in our project.
