我有这个代码用于验证从WCF服务创建的Customer类:
public partial class Customer : IDataErrorInfo
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int Age { get; set; }
#region IDataErrorInfo Members
public string Error
{
get { throw new NotImplementedException(); }
}
public string this[string columnName]
{
get
{
string result = null;
if (columnName == "FirstName")
{
if (string.IsNullOrEmpty(FirstName))
result = "Please enter a First Name";
}
if (columnName == "LastName")
{
if (string.IsNullOrEmpty(LastName))
result = "Please enter a Last Name";
}
if (columnName == "Age")
{
if (Age < = 0 || Age >= 99)
result = "Please enter a valid age";
}
return result;
}
}
#endregion
}
我在this [string columnName]方法的定义中得到了错误,可能是因为它是一个部分类:
Member names cannot be the same as their enclosing type
你知道如何解决这个问题吗?
答案 0 :(得分:0)
所有这些都告诉您,您的会员名称不能与班级名称相同。例如,您不能在Customer对象上拥有Customer方法或属性。
例如提防
public class Customer
{
public void Customer() //<- You cannot do this, remove the void Customer should only be the constructor
{ }
}
所以我猜这个问题是在其他地方,而不是你发布的代码片段。
