Question

我通过在控制台应用程序中创建的lists.asmx的服务引用访问SharePoint（2007）列表。控制台应用程序在VS2012和.Net 4.5框架中创建。

ListsSoapClient proxy1 = new ListsSoapClient();
proxy1.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
proxy1.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;    
string listName = "List_For_Test";
DataSet ds1 = new DataSet();
XElement ndQuery = new XElement("Query", "");
XElement ndViewFields = new XElement("ViewFields", "");
XElement ndQueryOptions = new XElement("QueryOptions", "");
XElement items = proxy1.GetListItems(listName, null, ndQuery, ndViewFields, null, ndQueryOptions, null);
ds1 = XElementToDataSet(items);

我需要将项目XElement中返回的XML转换为dataset / datatable，并将其传递给用SQL Server 2008 R2编写的存储过程。

我尝试使用以下代码，但它给了我错误

    XElement setup = (from p in x.Descendants() select p).First();
    foreach (XElement xe in setup.Descendants()) // build your DataTable
    dt.Columns.Add(new DataColumn(xe.Name.ToString(), typeof(string))); 
    // on second iteration gave error that "'{#RowsetSchema}row'" column already existing.

这是从GetListItems（）webservice方法调用

返回的XML流

Answer 1

请检查here...

class App extends Component {
  constructor() {
    super();
     this.state = {
        checkids:{
          'cfc0': false,
          'cfc1': false, 
          'cfc2': false,
          'cfc3': false
        }
     };
  }

  handleCheck(e) {
     const checkids = {...this.state.checkids};
     checkids[e.target.id] = e.target.id === "cfc1" ? false : !checkids[e.target.id];

     this.setState({checkids});
  }

  getElements() {
     let arr = [];
     Object.keys(this.state.checkids).forEach(function(element, index) {
        arr.push(
          <Checkbox
             key={index}
             id={element}
             checked={this.state.checkids[element]}
             onCheck={this.handleCheck.bind(this)}
          />
        );
     }, this)
     return arr;
  }

  render() {
    return (
      <MuiThemeProvider>
        <div>
          {this.getElements()}
       </div>
      </MuiThemeProvider>
    );
  }
}

像这样使用：

public static class XElementExtensions {
public static DataTable ToDataTable(this XElement element) {
    DataSet ds = new DataSet();
    string rawXml = element.ToString();
    ds.ReadXml(new StringReader(rawXml));
    return ds.Tables[0];
}

public static DataTable ToDataTable(this IEnumerable<XElement> elements) {
    return ToDataTable(new XElement("Root", elements));
}
}

}

khushi，检查这可能对你有用....

public static DataSet XElementToDataSet(XElement xeRecordsList)
{
  DataTable dtRecordsList = new DataTable();

  XElement setup = (from p in xeRecordsList.Descendants() select p).First();
  // builds DataTable
 foreach (XElement xe in setup.Descendants())
 dtRecordsList.Columns.Add(new DataColumn(xe.Name.ToString(), typeof(string)));
 // add columns to your dt

var all = from p in xeRecordsList.Descendants(setup.Name.ToString()) select p;
foreach (XElement xe in all)
{
 DataRow dr = dtRecordsList.NewRow();

 //adding the values
 foreach (XElement xe2 in xe.Descendants())
 {
   bool boolColExists = false;
   //Check for column exists in datatable
   foreach (DataColumn col in dtRecordsList.Columns) 
   {
      if (col.ColumnName == xe2.Name.ToString())
      {
        boolColExists = true;
        break;
      }
   }
  if (boolColExists)
  dr[xe2.Name.ToString()] = xe2.Value;
 }
 dtRecordsList.Rows.Add(dr);
}
DataSet dstRecordsList = new DataSet("RECORDLIST");
dstRecordsList.Tables.Add(dtRecordsList);
dstRecordsList.Tables[0].TableName = "RECORD";
return dstRecordsList;
}
