This is how we do it in multiple steps, however same can be done in single line.
var lst=new ExternalTypeCd()
{
ExternalIdTypeName="ABC",
SiteCode ="DEF"
}
var lstt=new ExternalTypeCd()
{
ExternalIdTypeName="ABC123",
SiteCode ="DEF123"
}
var siteExternalIdItem=new SiteExternalIdItem()
{
ExternalIdTypeCd=lst,
SiteNumber="1234"
}
var siteExternalIdItem2=new SiteExternalIdItem()
{
ExternalIdTypeCd=lstt,
SiteNumber="12345"
}
var SiteExternalIdItemArr= new SiteExternalIdItem[]
{
siteExternalIdItem,siteExternalIdItem2
}
SiteExternalId obj= new SiteExternalId[];
obj.item= SiteExternalIdItemArr;

always use var when you use initializer as below. var lst=new ExternalTypeCd(){ExternalIdTypeName="C#",SiteCode ="DEF"}

In one line do like this

var SiteExternalId = new SiteExternalId
{
Item = new SiteExternalIdItem[]
{
new SiteExternalIdItem()
{
ExternalIdTypeCd=
new ExternalTypeCd()
{
ExternalIdTypeName="ABC123",
SiteCode ="DEF123"
}
,
SiteNumber="1234"
},
new SiteExternalIdItem()
{
ExternalIdTypeCd=
new ExternalTypeCd()
{
ExternalIdTypeName="ABC",
SiteCode ="DEF"
}
,
SiteNumber="12345"
}
}
}

Thanks Sachin,

I'm trying this way, but not success

SiteExternalId = new SiteExternalId
{
Item = new SiteExternalIdItem[]
{
new ExternalTypeCd {ExternalIdTypeName = "A", SiteCode = "X"}
}
},

If possible could you give me initialization in a single line. Thanks

Thanks a lot Sachin for your support.
