C# - Cannot convert convert lambda expression to listitem
Title="xxxxxxx yyyyyyy zzzzzz 1234RED 987";
Value="1234RED";
if (!dialogItems.Exists(x => x.Title == value))
throw new InvalidOperationException($"List does not have {value}.");
above code is working fine which will compare with title.
I need to compare the values by Contains instead of Title
need direction
other words - Partial string matches are allowed
c# c#-4.0

You can use below variants of lambda expression to validate Contains
A) You can check if Title contains value with
1) Exist
if (!dialogItems.Exists(x => x.Title.Contains(value)))
OR
2) Any
if (!dialogItems.Any(x => x.Title.Contains(value)))
B) You can check if Title contains value with trimming all leading and trailing white spaces and lowering the case of both title and value. It causes more chances to match your value with Title
1) Exist
if (!dialogItems.Exists(x => x.Title.Trim().ToLower().Contains(value.Trim().ToLower())))
OR
2) Any
if (!dialogItems.Any(x => x.Title.Trim().ToLower().Contains(value.Trim().ToLower())))
