    <OutAttribute> ByRef status As Status() _
)
'Usage

)

Parameters

    Type: System.String
    The Excel Web Services session ID.

The Recalculate type will calculate only those formulas that have been changed.

The CalculateFull type will calculate all formulas, but without rebuilding the dependency tree.

Examples

//Instantiate the Web service 
//and make a status array object.
ExcelService es = new ExcelService();
Status[] outStatus;
string sheetName = "FormulaSheet";

//If workbookPath is a UNC path, the application 
//must be on the same computer as the server.
string targetWorkbookPath = @"\\localhost\xlfiles\Formulas.xlsx";

//Set Credentials for requests
es.Credentials = System.Net.CredentialCache.DefaultCredentials;
try
{
    //Call open workbook, and point to the trusted 
    //location of the workbook to open.
    string sessionId = es.OpenWorkbook(targetWorkbookPath, "en-US", "en-US", out outStatus);

    //Recalculate the workbook.
    es.CalculateWorkbook(sessionId, CalculateType.Recalculate);

    //Close workbook. This also closes the session.
    es.CloseWorkbook(sessionId);
}
