问题 I've run into a problem with a dotnet core 3.1 application that's designed to run as a windows service. The project originates from the Worker Service template in VS2019.

问题 How do I find the DataType of Metadata.IProperty in Entity Framework Core? var tableType = _dbContext.Model.GetEntityTypes().First(c => c.GetTableName() == tableName); foreach (var property in tableType.GetProperties()) { var test = property.PropertyInfo.PropertyType.Name; Using property.PropertyInfo.PropertyType.Name , sometimes works, however for nullable objects it prints null. I am looking for a clean way to get data type. 回答1: The Type of the IProperty is represented by ClrType property.
