T4: Use a tree array to find reverse order PairsA [I] is the prefix andDerivation (A [J]-A [I])/(J-I)> = mA [J]-A [I]> = m (J-I)A [J]-M * j> = A [I]-M * IB [J]> = B [I]This is the reverse order.Next, let's learn how to use a tree array.The principle is: the tree array is used to calculate the Range Sum, right?That is, statistics by weight range can be maintained by bit...Scan it againThat is, how many Reverse Order pairs are computedThe interval stati

Visual Studio 2013 EF5 Object Data Model edmx uses the inherited object dbcontext generated by the T4 template. The familiar objectcontext object is missing. Of course, not every programmer needs the objectcontext object, there are two solutions: Method 1. open model. Context. CS and add Public oraclemodelentities (objectcontext, bool dbcontextownsobjectcontext): Base (objectcontext, dbcontextownsobjectcontext){} As follows: using System; using

Label:There is a workaround on the internet as follows: Http://www.cnblogs.com/stone_w/archive/2012/10/25/2738345.html But I tried. It's too much trouble, and once the EF is rebuilt and rebuilt. Later I queried the information, can use the T4 template to solve this problem. 1. Download file getsummery.ttinclude, here I have provided, everyone to download: download 2. Unzip the files we downloaded and put the extracted files into the solution3. Modify

defined the recursive type.So, just construct the matrix a ={1 1 5 31 0 0 00 0 1 10 0 1 0}Among them, the transverse four numbers are respectively represented Ans[i-1],ans[i-2], f[i-1], f[i-2]Portrait four numbers respectively Ans[i],ans[i-1], F[i], f[i-1]Then we use the N-2 power of this matrix to multiply the vector b ={5021}These four numbers represent ans[2],ans[1], f[2], f[1].After multiplying to get a matrix of 4 * 1, the answer is the number in the first column of the first row.When calc

When the EF Power Tools database is reverse generated, the T4 template is modified, and the eft4 On VS2013, the Reverse Engineer Code First of EF Power Tools is used for Reverse generation. It is found that the decimal (18, 4) field in the database has no precision or decimal places in the generated mapping class. This enables the automatically generated SQL statement to use decimal (18, 2) by default when saving data through EF ). Fortunately, EF Pow

first, the definition of T4 template and the generation of code files Let's take a look at what the final code generation needs to define, and how the T4 template should be defined. For this framework, the generation of code structures is implemented by inheriting custom types from our custom base class template. As a demo, we define a demotemplate as follows. As you can see from the code, Demotemplate is

Microsoft Visual Studio contains a code generation engine called the T4 (abbreviation for the text Template Conversion Toolkit). You may have used the T4 template in Visual Studio, and you don't even know that the templates are already working in the background. In this article, I'll briefly introduce the T4 template and explain how ASP.net MVC uses this technolo

The use of T4 template, can be very convenient from the database map into model models, equivalent to the effect of dynamic and soft. But the soft is can directly generate three layers, abstract factory, T4 not so bull, so we generally only used to generate Modle or server and other specified methods. Talk less, cut to the chase: I'll explain in two parts, part of which is to build the method attributes int
