DataTable上的RowFilter以在gridview中显示

// 创建一个DataTable对象
DataTable dataTable = new DataTable();

// 假设DataTable中有以下列：ID、Name、Age、Gender

// 添加列
dataTable.Columns.Add("ID", typeof(int));
dataTable.Columns.Add("Name", typeof(string));
dataTable.Columns.Add("Age", typeof(int));
dataTable.Columns.Add("Gender", typeof(string));

// 添加行数据
dataTable.Rows.Add(1, "John", 25, "Male");
dataTable.Rows.Add(2, "Jane", 30, "Female");
dataTable.Rows.Add(3, "Tom", 35, "Male");
dataTable.Rows.Add(4, "Alice", 28, "Female");

// 设置RowFilter条件
string filterExpression = "Age > 25 AND Gender = 'Female'";
dataTable.DefaultView.RowFilter = filterExpression;

// 将筛选后的结果绑定到GridView控件
GridView1.DataSource = dataTable.DefaultView;
GridView1.DataBind();
