C# Enum generation - underlying int values do not match the original enum
I created an enum on my server with integer values set manually rather than the default increment up from 0 public enum UserType { Anonymous = 0, Customer = 10, Technician = 21, Manager = 25, Primary = 30 } I am using AspNetCore.App 2.2.0 and swashbuckle aspnetcore 4.0.1 to generate my CSharp API client The generated enum in the c sharp api client (using NSwag Studio for windows v 13.2.3.0) looks like this - the underlying integer values do not match the original enum. [System.CodeDom.Compiler.GeneratedCode("NJsonSchema", "10.1.5.0 (Newtonsoft.Json v11.0.0.0)")] public enum UserType { [System.Runtime.Serialization.EnumMember(Value = @"Anonymous")] Anonymous = 0, [System.Runtime.Serialization.EnumMember(Value = @"Customer")] Customer = 1, [System.Runtime.Serialization.EnumMember(Value = @"Technician")] Technician = 2, [System.Runtime.Serialization.EnumMember(Value = @"Manager")] Manager = 3, [System.Runtime.Serialization.EnumMember(Value = @"Primary")] Primary = 4, } This creates a problem for me client side as there are situations where I need to know the integer value. I am looking for a solution where I can avoid writing converters every time I want to know the integer value on the client side. Option 1: Is there an option I am missing in either NSwag Studio or in .net configuration (my Startup.Cs config is below for reference) where I can force the generated enums to get the same integer values as the original enum? Option 2: Alternatively if not, both my client and my server have access to the same original enum via a shared class library. Is there a way to get the generated api client to use the actual original enums in the apiclient.cs rather than generate its own? Reference: The enums part of my swagger generation code in Startup.Cs looks like this services.AddJsonOptions(options => { options. SerializerSettings.Converters.Add(new StringEnumConverter()); ....services.AddSwaggerGen(setup => { setup.SwaggerDoc("v1", new Info { Title = AppConst.SwaggerTitle, Version = "v1" }); setup.UseReferencedDefinitionsForEnums(); ... other stuff... } Matching SO question if you want some rephttps://stackoverflow.com/questions/60222469/swagger-c-sharp-enum-generation-underlying-int-values-do-not-match-the-origina
