c# - Cannot implicitly convert type 'System.Linq.IQueryable' to 'System.Collections.Generic.IList' -


मेरे पास एक विधि है: 

  सार्वजनिक डिजीओकोऔरऑप्कीकुणकॉल्यूशन GetChildAndOpiekunByFirstnameLastname (स्ट्रिंग प्रथमनाम, स्ट्रिंग लास्ट नेम) { DataTransfer.ChargeInSchoolEntities डीबी = नया डेटाट्रांस्फर.ChargeInSchoolEntities (); डिज़ेकॉऔपिक्कनकॉलन्यूशन परिणाम = नया डीज़ेक्कोऔरऑपिकुण संकलन (); अगर (प्रथम नाम == रिक्त और amp; अंतिम नाम! = नल) {आईएलआईटी & lt; डीजीओ एंड ओपीकन & gt; परिणाम V = db.Dziecko में p से जहां अंतिम नाम == पी। नजविस्को ** का चयन करें ** नया डिज़ेको एंड ओपीक्यून (पी। आईमी, पी। नजविस्को, पी। ऑफीक। आईएमआई, पी ओपीकन नाज़विस्को); result.AddRange (resultV); } वापसी परिणाम; }

और चुने हुए स्थान में त्रुटि:

त्रुटि 1 पर आधारित 'System.Linq.IQueryable & wtfService1.DzieckoAndOpiekun & gt; करने के लिए 'System.Collections.Generic.IList & lt; WcfService1.DzieckoAndOpiekun & gt;' एक स्पष्ट रूपांतरण मौजूद है (क्या आप एक कलाकार को नहीं छोड़ रहे हैं?)

कोई भी विचार मेरी समस्या कैसे हल करता है?

सूची में IQuerable या IEnumerable को परिवर्तित करने के लिए, आप निम्न में से एक कर सकते हैं: 

  IQueryable & LT; वस्तु & gt; Q = ...; सूची के & lt; वस्तु & gt; L = q.ToList ();

या:

<पूर्व> IQueryable & lt; ऑब्जेक्ट & gt; Q = ...; सूची के & lt; वस्तु & gt; L = नई सूची & lt; ऑब्जेक्ट & gt; (q);

wpf - accessing a visual element in code -

I want to match the following xaml in the code, but I do not know how to capture that text block element: & lt; Local: Deaf TheWeekColumn ... & lt; Local: TheWeekColumn.Header & gt; & Lt; TextBlock Text = "{binding ...}, tooltip =" {binding ...} /> & Lt; / Local: DayOfTheWeekColumn.Header & gt; & Lt; / Local: DayOfTheWeekColumn & gt; The DayOfTheWeekColumn is a subclass of a DataGridTextColumn. I can easily get it on the header and set it to my content, and now I want to set the tooltip in the code, to find out how to do it in xaml above. Cheers, Berryl Edit ========= Even Code for DayOfTheWeekColumn is. XML is part of the text book headers' visual tree, and nothing else I want to put in XML. I want to put it in the tooltip, however, is in the code, so I can set it there. I am thinking that the column headers should have the property of a child, which I can use to find the text box, but the haven has not been found yet....

I want to control the visibility of the image in a button through a trigger: & lt; Button x: name = "notespanel" command = "{binding adddocument}" & gt; & Lt; Image x: name = "notes image" source = "notes" "height =" 32 "& gt; & gt; & gt; & gt; button & gt; 1 / What trigger will appear in the button or in the container that faces the button? 2 / How to set the visibility of the image? Thanks Zone Since you are updating the image, it should lie with the image (style of image as part) such as if the image is by default Is hidden, so I try the following Using R can choose to make it visible with toggleproperty1. DataTrigger binding = "{binding toggleproperty}" value = "1" & gt; & lt ; Setter Property = "Visibility" value = "View" />
