how to convert array to BindingList

Question

将数组转换为BindingList最简单快捷的方法是什么？

Answer 1

使用带有IList<T>的BindingList构造函数。

var binding = new BindingList<MyType>(myArray);

Answer 2

Be careful when using the BindingList(IList ..) constructor with an Array as the IList will be read-only.

Any attempts to add/remove from the BindingList will therefore throw a NotSupportedException as the IList can't handle the functionality as the Collection is read-only.

To create an editable BindingList you'll have to convert it to a list before using the IList constructor.

A nice description as to why Arrays are built from IList can be found here for some additional reading: Why array implements IList?

Answer 3

你正在寻找构造函数 ：

var bl = new BindingList<YourClass>(arr);

Answer 4

you can try a foreach cycle:

    public void AppenFromArray(T[] aSource)
    {
        if (aSource == null) { return; }

        foreach (T el in aSource)
        {
            this.Add(el);
        }
    }
