我正在使用DataTable填寫我的DataGridView的信息。然後,我用的BindingSource使用過濾上的數據:現在如何將BindingSource轉換爲DataTable?
BindingSource bs = new BindingSource();
bs.DataSource = dgvAppList.DataSource;
bs.Filter = ""; //some filter commands here
dgvAppList.DataSource = bs;
,過濾後,我想將數據從我的上一個DataTable的DataGridView存儲。我試着用下面的代碼:
var bindingSource = (BindingSource)dgvAppList.DataSource;
var table = (DataTable)bindingSource.DataSource; // error pops out here
但我總是最後得到的錯誤:
Unable to cast object of type 'System.Windows.Forms.BindingSource' to type 'System.Data.DataTable'.
我怎麼會投BindingSource的數據表來存儲數據表變量我的DataGridView的數據?
