Asp.net Identity UserManager錯誤：UserName爲空

Question

UserManager CreateAsyncy給出錯誤：UserName不能爲空或爲空。

下面是我的代碼片斷：

var contractor = new Contractor() 
       { 
        UserName = contractorModel.UserName, 
        Email = contractorModel.Email, 
        EmailConfirmed = true, 
        SecurityStamp = Guid.NewGuid().ToString() 


       }; 
       var result = await UserManager.CreateAsync(contractor,"Passw0rd!"); 

Answer 1

我的UserName = contractorModel.Email固定它;
