Question

我试图将多重价值观列入一个选择清单:

SelectList List = new SelectList(MyListItems, "valField", "dataField", <selected values>);

我在选择多个项目时使用了什么目标/价值?

Answer 1

http://msdn.microsoft.com/en-us/library/d470159.aspx” rel=“noreferer” 而后者则拥有满足你们需求的建筑:

public MultiSelectList(
    IEnumerable items,
    string dataValueField,
    string dataTextField,
    IEnumerable selectedValues
)

Answer 2

例:

class Person
{
    int Id{ get; set; }
    string Name { get; set; }
}

...

var people = new List<Person>()
{
    new Person{ Id = 1, Name = "Steve" },
    new Person{ Id = 2, Name = "Bill" },
    new Person{ Id = 3, Name = "John" },
    new Person{ Id = 4, Name = "Larry" }
}
SelectList List = new MultiSelectList(people, "Id", "Name", new[]{ 2, 3 });
