. Net Entity Framework Core configures floating-point precision with Hascolumntype

First, preface

The previous time with the. NET Entity Framework core Framework, you need to configure the precision of floating-point numbers, and found that the. NET Entity Framework core does not have a hasprecision method. Find less information on the web, and finally, with official documentation, try using Hascolumntype to configure floating-point accuracy successfully.

Iii. comparing the. NET Entity Framework and the. NET Entity Framework Core Configuration

. Net Entity Framework Methods:

 Public classmyprojectcontext:dbcontext{ PublicDbset<order> Orders {Get;Set; } protected Override voidonmodelcreating (Dbmodelbuilder modelBuilder) {Base. Onmodelcreating (ModelBuilder);
            //to configure the amount of an order floating point precision is decimal (18,6)modelbuilder.entity<Order> (). Property (t = t.amount). Hasprecision ( -,6); }   }

The. Net Entity Framework Core method:

 Public classmyprojectcontext:dbcontext{ PublicDbset<order> Orders {Get;Set; } protected Override voidonmodelcreating (Dbmodelbuilder modelBuilder) {Base.            Onmodelcreating (ModelBuilder); Modelbuilder.entity<Order> (b ={//to configure the amount of an order floating point precision is decimal (18,6)B.property (P= P.amount). Hascolumntype ("decimal (18,6)");   　　　　 }); }   }
