将List<T>转换为BindingList<T>,然后设置DataGridView的DataSource为BindingList<T>!!
代码:
DataGridView.DataSource = new BindingList<T>(List<T>);
将绑定BindingList<T>的DataSource转化为List<T>,同理
代码:
List<T> modelList=new List<T>((BindingList<T>)this.DataGridView.DataSource);
说明:BindingList<T>和List<T>都有个构造函数,参数是IEnumerable<T>,既然他们俩个都是继承IEnumerable,当然能相互转换。
下面是这个构造函数的执行过程:
public List(IEnumerable<T> collection)
{
if (collection == null)
{
ThrowHelper.ThrowArgumentNullException(ExceptionArgument.collection);
}
ICollection<T> is2 = collection as ICollection<T>;
if (is2 != null)
{
int count = is2.Count;
this._items = new T[count];
is2.CopyTo(this._items, 0);
this._size = count;
}
else
{
this._size = 0;
this._items = new T[4];
using (IEnumerator<T> enumerator = collection.GetEnumerator())
{
while (enumerator.MoveNext())
{
this.Add(enumerator.Current);
}
}
}
}
{
if (collection == null)
{
ThrowHelper.ThrowArgumentNullException(ExceptionArgument.collection);
}
ICollection<T> is2 = collection as ICollection<T>;
if (is2 != null)
{
int count = is2.Count;
this._items = new T[count];
is2.CopyTo(this._items, 0);
this._size = count;
}
else
{
this._size = 0;
this._items = new T[4];
using (IEnumerator<T> enumerator = collection.GetEnumerator())
{
while (enumerator.MoveNext())
{
this.Add(enumerator.Current);
}
}
}
}
