I'm using Excel 2010 and I need to open and import XML files using C# It seems that the key to performing this is to use XmlImportXml on the workbook object. Trouble is I'm not sure how to use it.
I have the datasource which is a string value of the XML streamed in. I know I want to set overwrite to true, and I set my importmap to null since I do not have one of these. The bit thats throwing me is that there is an out parameter of type XmlMap, the
documentation seems to state I can leave this if I have a destination range. I have a Destination of (Range("$A$1")) to use. can anybody give an example of using this in C#

There is an example on MSDN
Here is the example which I've updated with your info - you need to specify the XML since I don't know how you are getting that:
private void WorkbookXmlImportEvents()
// Just a little debugging - remove if you don't need it
this.AfterXmlImport += new
// Add a new XML map to the collection.
Excel.XmlMap xmlMap1 = this.XmlMaps.Add(xmlSchemaAsStringOrFileLocation,
// Import the data stream if the XmlMap was successfully created.
if (xmlMap1 != null)
// Get objects that can be used while the ExcelLocale1033
// attribute is true (the default).
Excel.Workbook workbook1 = (Excel.Workbook)Microsoft.Office.Tools.
Excel.Range range1 = Globals.Sheet1.Range["A1", missing];
range1 = (Excel.Range)Microsoft.Office.Tools.Excel.
xmlMap1 = (Excel.XmlMap)Microsoft.Office.Tools.Excel.
// This will raise the BeforeXmlImport and AfterXmlImport events.
workbook1.XmlImportXml(xmlAsString, out xmlMap1, true,
MessageBox.Show("The XmlMap could not be created");
void ThisWorkbook_BeforeXmlImport(Excel.XmlMap Map,
string Url, bool IsRefresh, ref bool Cancel)
if (DialogResult.No == MessageBox.Show("Microsoft Excel is about" +
" to import XML into the workbook. Continue with importing?",
"Custom XML Import Dialog", MessageBoxButtons.YesNo))
Cancel = true;
void ThisWorkbook_AfterXmlImport(Excel.XmlMap Map, bool IsRefresh,
if (Result == Excel.XlXmlImportResult.xlXmlImportSuccess)
MessageBox.Show("XML import succeeded.");
MessageBox.Show("XML import failed.");
