我正在使用fetchxml查询来获取CRM动态的结果但是如果我的fetchxml有6个属性并且查询这个我得到的属性少于6个,原因是,如果行有空/空值则它不会返回属性名称,我需要属性名称,因为我编写了代码来获取属性名称并从属性名称动态获取数据。 她是我的代码。
假设我的fetchxml包含这样的字符串(注意:我从视图名称动态获取字符串,只显示字符串)
string fetchxml= @"<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>
<entity name='cdi_postedsurvey'>
<attribute name='cdi_postedsurveyid' />
<attribute name='cdi_name' />
<attribute name='createdon' />
<order attribute='cdi_name' descending='false' />
<filter type='and'>
<condition attribute='statecode' operator='in'>
<value>1</value>
<value>0</value>
</condition>
<condition attribute='cdi_postedsurveyid' operator='not-null' />
<condition attribute='createdon' operator='on-or-after' value='2016-09-09' />
<condition attribute='createdon' operator='on-or-before' value='2016-09-13' />
</filter>
</entity>
</fetch>";
EntityCollection _viewResult = _orgService.RetrieveMultiple(new FetchExpression(_fetchxml));
foreach (var e in _viewResult .Entities) **//Here the entity return less attributes because the row is blank**
{
if (_keycnt == 0)
{
foreach (var keys in e.Attributes.Keys)
{
_csvData.AppendFormat(keys + ","); //Get all the Attribute names in comma separted format.
}
_splitIntoColumn = _csvData.ToString().TrimEnd().Split(',');
}
_keycnt = 1;
_csvData.Remove(_csvData.ToString().LastIndexOf(","), 1); //Removes comma from the end of the string
_csvData.AppendLine(); //Enters new line
for (int j = 0; j < _splitIntoColumn.Length - 1; j++)
{
string _attributeName = _splitIntoColumn[j].ToString();
//Now get the values based on attribute name
if (e.FormattedValues.Contains(_attributeName))
{
//append data in csv file
}
这是我在我的CSV文件中获得的,其中我有4个属性,但我得到3,因为第一行是空白的。
cdi_postedsurveyid createdon logicalname
A 14-09-2011 sample
B 14-09-2011 sample
这就是我想要的,即使第一行为空,也包括cdi_name
cdi_name cdi_postedsurveyid createdon logicalname
A 14-09-2011 sample
test data B 14-09-2011 sample
test data B 14-09-2011 sample

$atts = $xml.GetElementsByTagName('attribute');
foreach($att in $atts)
{
if($att.ParentNode.HasAttribute('alias'))
{
$attName = $att.ParentNode.GetAttribute('alias') + "." + $att.name
Write-Output $att.ParentNode.GetAttribute('alias') + "." + $att.name
}
else
{
$attName = $att.name
Write-Output $att.name
}
Add-Member -InputObject $psobj -MemberType NoteProperty -Name $attName -Value $null
Add-Member -InputObject $psobj -MemberType NoteProperty -Name ($attName + "_Property") -Value $null
