推荐答案

VS从创建数组时使用的变量类型(在本例中为userID)派生数组的类型，有两种解决方法:

VS is deriving the type of the array from the type of the variable used in its creation (in this case userID), there are 2 ways around this, either:

object[] parameters = new[] { (object)UserID };

或

or

object[] parameters = new object[] { UserID };

就个人而言，我更喜欢第二个选项.

Personally, i prefer the 2nd option.

为您提供一些建议:

private Int32 UserID;
private Int32 AdminID;
private List<Int32> ListOInt32s;
private List<object> ListOObjects;

private void MakeIDS(Int32 uID, Int32 aID)
{
    UserID = uID;
    AdminID = aID;

    // anonymous type
    // exists only in the scope of this method call
    var IDS = new {UserID, AdminID};

    // generic strongly typed
    ListOInt32s = new List<Int32> {UserID, AdminID};

    // generic typed as Object
    ListOObjects = new List<object> {UserID, AdminID};
}

private void button1_Click(object sender, EventArgs e)
{
    MakeIDS(4,5);
}

这可能会有所帮助，

It might be helpful,

static void Main(string[] args)
{
    Int32 one = 1, two = 2;
    object[] myArray = { one, two };
}
