Question

我是.Net框架的新手，但收到一条错误消息

类型'List（Of AdminSetEmployeeParams）'的值不能转换为 'AdminSetEmployeeParams'“

Dim SetNewEmployee As New List(Of AdminSetEmployeeParams)

  SetNewEmployee.Add(New AdminSetEmployeeParams With {
                    .departmentId = ddlDept.SelectedValue,
                    .familyName = txtLastOrSurname.Text,
                    .firstName = txtFirstOrGivenName.Text,
                    .secondName = txtSecondName.Text,
                    .contactPhone = txtPhone.Text,
                    .user = ""})

SetNewEmployee = EmployeeAPIService.AdminSetEmployee(SetNewEmployee).Result

如何解决此错误？

更新：

System.Threading.Tasks
Public Class Task(Of TResult)


Public ReadOnly Property Result As TResult

可能是这样，但是很难确定：

Dim newEmployee As New AdminSetEmployeeParams

newEmployee = New AdminSetEmployeeParams With {
                .departmentId = ddlDept.SelectedValue,
                .familyName = txtLastOrSurname.Text,
                .firstName = txtFirstOrGivenName.Text,
                .secondName = txtSecondName.Text,
                .contactPhone = txtPhone.Text,
                .user = ""})

Dim newEmployeeResult As List(Of AdminSetEmployeeParams) = EmployeeAPIService.AdminSetEmployee(newEmployee).Result

我不确定您的API为什么在其结果中返回一个雇员列表（我假设是这样，因为您没有说您有一条错误消息，抱怨将结果分配给一个列表。 ..）），但给定的错误只会在API调用要求一位新员工并且您将新员工列表交给您的情况下才会发生

如果无法解决，请尝试最后一行

Dim newEmployeeResult As AdminSetEmployeeParams = EmployeeAPIService.AdminSetEmployee(newEmployee).Result

如果仍然无法解决，请编辑您的问题，以详细了解AdminSetEmployee接受哪种参数以及对象是什么类型。Result

在VB.Net中创建列表对象时出错
