英文:
There is a way to set entities dynamically based on model string name in odata asp net core web api?
问题
我正在尝试基于string name或variable types在odata中动态注册实体。
var modelBuilder = new ODataConventionModelBuilder();
modelBuilder.EntitySet<Employee>("Employees");
modelBuilder.EntitySet<Manager>("Managers");
我正在尝试寻找一种动态的方法。

I am trying to register entities dynamically in odata based on string name or variable types.
var modelBuilder = new ODataConventionModelBuilder();
modelBuilder.EntitySet<Employee>("Employees");
modelBuilder.EntitySet<Manager>("Managers");
I am using this way but trying to find dynamic one.

你可以使用反射来实现，例如使用实体名称字符串变量注册 "empolyee"：
string entityName = "Employee";
在创建 ModelBuilder 后，使用以下代码来执行 modelBuilder.EntitySet<Employee>("Employees"); 使用反射：
Type entityType = Type.GetType($"EmployeeNamespace.{entityName}");
var entitySetMethod = typeof(ODataConventionModelBuilder).GetMethod("EntitySet");
var genericEntitySetMethod = entitySetMethod.MakeGenericMethod(entityType);
genericEntitySetMethod.Invoke(modelBuilder, new object[] { entityName });
英文:
You can use reflection to achieve, For example register "empolyee" with entityName string variable:
string entityName = "Employee";
After create modelbuilder, use the following code to execute modelBuilder.EntitySet<Employee>("Employees"); with Reflection.
Type entityType = Type.GetType($"EmployeeNamespace.{entityName}");
var entitySetMethod = typeof(ODataConventionModelBuilder).GetMethod("EntitySet");
var genericEntitySetMethod = entitySetMethod.MakeGenericMethod(entityType);
genericEntitySetMethod.Invoke(modelBuilder, new object[] { entityName });
