3. Get list information

try
{
WebServices1.Lists listService = new GetListTest.WebServices1.Lists();
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;
XmlNode ndLists = listService.GetList("Test");//参数列表名，String类型
Console.Write(ndLists.OuterXml);
}
catch (Exception ex)
{
Console.Write(ex.Message);
}

4. Get list information results

//获取ListItem信息
WebServices1.Lists listService = new GetListTest.WebServices1.Lists();
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;
XmlDocument xmlDoc = new System.Xml.XmlDocument();
XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
XmlNode ndViewFields = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");
XmlNode ndQueryOptions = xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", "");
ndQueryOptions.InnerXml = ""; //Query设置
ndViewFields.InnerXml = ""; //视图设置
ndQuery.InnerXml = ""; //Caml语句
try
{
XmlNode ndListItems = listService.GetListItems("Test", null, ndQuery, ndViewFields, "1", ndQueryOptions, null); //获取列表内容
Console.Write(ndListItems.OuterXml); //输出获取的Xml内容
}
catch (System.Web.Services.Protocols.SoapException ex)
