How Can I .Deserialize Expression<Func<T, dynamic>>

[yangmail2002]

I have a Expression :
Expression<Func<T, dynamic>> exp=s => new { s.Name, s.ProductCategoryID }
serialize it to string . But When I deserialize this string ,it retun null with error " 序列不包含任何匹配元素"
The seialize string is 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
