I'm not sure if you read my comment, but I specifically said that C# and Java share the same syntax.
C# and VB.NET share lambdas, linq, anonymous functions, delegates. They share the same implementation of generics (which is different than Java), the same type system (which is different than Java, enums, nullables), covariance, contravariance. They share the same frameworks (WPF, Silverlight, WebForms, WinForms, MVC, ...), and the same IDE and other tooling. They share the same patterns: deterministic finalization, asynchronous programming, fluent interfaces. They share the same language shortcuts: auto-properties, properties, collection initializers, ...
Java and C# share braces, semi-colons, &&.
Java and C# are more similar for about 30 seconds.
