It is written in C#.NET.
If there is a code like the one below, I would like to use a conditional expression (IF statement) in the middle. Is it possible to write it down?
If possible, how do you write it?
prate List<UserInfo>[ ] usersList=newList<UserInfo>[8];
usersList=newList<UserInfo>{
new UsersInfo {No=1,FileName="book1.xlsx"sheet=3},
new UsersInfo {No=2, FileName="book1.xlsx"sheet=3},
new UsersInfo {No=3, FileName="book1.xlsx"sheet=4},
new UsersInfo {No=4, FileName="book1.xlsx"sheet=1},
★★★ At this time, I would like to change the FileName value of ↑↑↑ by condition★★★
↓↓↓ It appears to be written as follows, but in this case, it is not readable when conditions increase.
new UsersInfo {No=4, FileName=(cond==2?"book3.xlsx":"book1.xlsx"), sheet=1)
★★★ Is there a way to write in IF?★★★
★★★ If I can write, how should I write it?★★★

I can't.
The syntax listed is simply calling the Add method by saying collection initializer, so if you want to include conditions when adding, be honest and call the Add method.
Write whatever function you want...
Isn't that what you're looking for?
Func<string>getFileName=()=>
{
if(cond==2)
{
return "book3.xlsx";
}
return "book1.xlsx";
};
usersList=newList<UserInfo>{
newUserInfo() {No=1, FileName="book1.xlsx", sheet=3},
newUserInfo() {No=1, FileName="book1.xlsx", sheet=3},
newUserInfo() {No=1, FileName="book1.xlsx", sheet=4},
newUserInfo() {No=1,FileName=getFileName(),sheet=1}
};
