In this article, I am going to discuss LINQ Where Filtering Method in C# with Examples. An Expression to set the Right property equal to. Where comes under the Filtering Operators category? Using String. This tutorial demonstrates using the `CompareTo ()` method, equality operators (`==`, `!=`), and other comparison operators (`<`, `>`, I get that String. How can I write a LINQ with a condition where RequestDate is greater than any of the dates in ListOfDates? I'm looking for something like Contains but works for comparisons. This article contains several examples you can use or modify to suit your needs. Linq namespace—this provides many extension methods, ones that act on collections. What is LINQ All Method in C#? Example to Understand LINQ All Method in C# using Value Type Example to Understand LINQ All Method in C# using String Type LINQ All Method with Complex Learn various techniques for comparing enum values in C#. Use the String:Compare (string,string,bool) method to explicitly express a case-insensitive complete string equality operation. e. Perhaps the StringComparison. " Case insensitive string equality comparison Use the String:Compare (string,string,bool) method to explicitly express a case-insensitive complete Learn how to compare and order string values, with or without case, with or without culture specific ordering. The date in the db is a datetime and records time. I would like to query the db for items with a date greater than or equal to a given date. If the user enters the search string "1/30/2014", they You can query a string as a sequence of characters in LINQ. Learn how to implement this with clear One of the most useful features of LINQ is orderby —this allows us to specify that a query sorts its results. Here we use the default int sort, which goes from low to high. Comparisons are used to sort a sequence of strings. For example String. NET we import the System. Entity Framework translates the LINQ queries into SQL queries, and SQL supports string comparisons using the Perhaps the StringComparison. When you compare strings, you define an order among them. We have used ToLower () with LINQ to SQL for years and I too think this should be solved in a better way by LINQ doing the translation. Sorting using standard List methods or linq is simple enough, but since these are text strings, I'm drawing a blank on figuring out how to take all values after a specific filter since you can't 1 Quoting from your comment "i am comparing user entered value to collection of objects i have, to search Customers having IDs less than or you can say greater than that entered by user. Employee. Ordinal was unnecessary and defaulted to a sane value. It is also number one issue new coders run into Creates a BinaryExpression that represents a "greater than or equal" numeric comparison. Linq Query Syntax and Linq Method Syntax with Examples. Compare (value) > 0 give you a greater than and less . Date comparison such as greater than, lesser than and equal works bit different in cosmos database as defined in this article. Once the sequence is in a known order, it's easier to search, both for In VB. In a query expression, we describe a command in terms of the In Entity Framework, you can use the greater-than operator (>) to compare string s. 1 Employee GetEmployeeByName(string name) { return Context. Compare or value. An Expression to set the Left property equal to. Here's an example of how you can use the greater-than operator Discover a simple way to filter a `List string ` in C# to find all strings greater than a specific value using LINQ. CompareTo is not supported by LINQ to Entities but is there another way to do this? It works if I convert it to an Enumerable but I would rather have the query run on the database for Equals Operator Not Equals Operator Method Based LINQ Query with Where Clause Greater Than Operator Greater Than or Equals and Less Than or Equals Operator Contain Operator I have the following class: public class Employee { public string Name {get; set;} } and a LINQ query in EF Core 2. Entity Framework translates the LINQ queries into SQL queries, and SQL supports string comparisons using the greater-than operator. A BinaryExpression that It works, if TKey is the same type as lowValue and highValue (both are int), but it doesn't work if lowValue and highValue are of the type string and TKey is still int. In this article, I am going to discuss the Different Ways to write LINQ Query i. The generated You can query a string as a sequence of characters in LINQ. CompareTo will allow you to do greater than or less than comparison on strings. Creates a BinaryExpression that represents a "greater than" numeric comparison. In EF7, the parser just punts when trying to compare strings and performs the comparison in-memory.
