Setup Open Live Writer and sync with Windows Live Writer cross computers
Today I am setting up a new PC. I use Windows Live Writer to write for this blog for years, and found the new installation can no longer work for my blog. I tried Open Live Writer. Fortunately Open Live Writer works.
LINQ to Objects in Depth (7) Building Custom Query Methods
With the understanding of standard queries in .NET Standard and the additional queries provided by Microsoft, it is easy to define custom LINQ queries for objects. This chapter demonstrates how to define the following useful LINQ to Object queries:
LINQ to Objects in Depth (6) Advanced Queries in Interactive Extensions (Ix)
The previous 2 chapters discussed the LINQ to Objects standard queries. Besides these built-in queries provided by System.Linq.Enumerable type in .NET Standard, Microsoft also provides additional LINQ to Objects queries through the System.Interactive NuGet package (aka Interactive Extensions library, or Ix). Ix has a System.Linq.EnumerableEx type with the following queries:
LINQ to Objects in Depth (5) Query Methods Implementation
Understanding of internal implementation of LINQ to Objects queries is the ultimate way to master them and use them accurately and effectively, and is also helpful for defining custom query methods, which is discussed later in the custom queries chapter. Just like the usage discussion part, here query methods are still categorized by output type, but in a different order:
LINQ to Objects in Depth (4) Deferred Execution, Lazy Evaluation and Eager Evaluation
As fore mentioned, when LINQ to Objects’ collection queries and value queries are called, they start to evaluate query result. When sequence queries are called, they do not evaluate any query result, and can be viewed as defining a query.
LINQ to Objects in Depth (3) Generator
After understanding how to use LINQ to Objects queries, this chapter starts to discuss how these queries work internally, including how they execute and how they are implemented. These insights help developer mastering LINQ to Objects.
LINQ to Objects in Depth (2) Query Methods (Operators) and Query Expressions
As fore mentioned, LINQ to Objects standard query methods (also called standard query operators) are provided as static methods of System.Linq.Enumerable type, most of which are IEnumerable<T> extension methods. They can be categorized by output type:
LINQ to Objects in Depth (1) Local Sequential Query
LINQ to Objects queries .NET objects in local memory of current application or service. Its data source and the queries are represented by IEnumerable<T> interface, and it is executed sequentially. This chapter introduces IEnumerable<T> interface, and discusses how to use LINQ to Object to query objects in query method syntax and query expression syntax.
