c# - LINQ to XML Replace Value Issue -

-

i having issue when trying replace value of xelement. not sure doing wrong. simplified xml follows

<payload>   <field name="slug_locator">     <value>orig value</value>   </field> </payload>

here query

ienumerable<xelement> fields =                     el in doc.descendants("field")                     el.attribute("name").value == "slug_locator"                     select el;  foreach (xelement el in fields)             {                 e.value = "new value";             }

if check el in each statement says value = orig value. assumed change , expect see this

 <payload>       <field name="slug_locator">         <value>new value</value>       </field>     </payload>

but , dont know why

 <payload>     <field name="slug_locator">new value</field> </payload>

any appreciated!

currently, you're selecting <field> element instead of <value> element. that's why entire content of <field> changed new value. can modify select part of linq slightest change fix problem :

ienumerable<xelement> values =                     el in doc.descendants("field")                     el.attribute("name").value == "slug_locator"                     select el.element("value");

or if need remain selecting <field>s, change for loop content :

foreach (xelement el in fields) {     el.element("value").value = "new value"; }

i'm defining 2 entities following, strange behavior occurring: [table("clienttypes", schema="dbo")] public clienttype { [key] public int id { get; set; } public string name { get; set; } } [table("clients", schema="dbo")] public client { [key] public long id { get; set; } [foreignkey("clienttypeid")] public int clienttypeid { get; set; } public virtual clienttype clienttype { get; set; } } i'm getting clienttypeid property filled value, clienttype object filled nothing. can me this? thank all! the foreignkey attribute have on wrong property. the annotation may placed on foreign key property , specify associated navigation property name, or placed on navigation property , specify associated foreign key name. - source [foreignkey("clienttypeid")] should decorate public virtual clienttype clienttype instead, or change [foreignkey("clienttype...
