DataTable利用内置函数过滤数据，RowFilter用法，写法如下：
string
strName = string.Empty;//查询条件 string
strSQL = string.Empty;//SQL DataView datav = dt.DefaultView; //利用Defaultview if
(!string.IsNullOrEmpty(textBox1.Text.Trim())) { strName = textBox1.Text.Trim(); } strSQL = " userName like ‘%"
+ strName + "%‘"; datav.RowFilter = strSQL; this.dgv_DataSource.DataSource = datav; |
利用DataTable的 select内置函数，写法如下：
string
strName = string.Empty;//查询条件string
strSQL = string.Empty;//SQLif (!string.IsNullOrEmpty(textBox1.Text.Trim())){ strName = textBox1.Text.Trim();}strSQL = " 1=1 And";strSQL += " userName like ‘%"
+ strName + "%‘";DataTable newdt = dt; //内存中的Datatable，原数据DataRow[] dr = dt.Select(strSQL);DataTable temp = dr[0].Table.Clone();//把搜索出来的DataRow转换成Datatableif (dr != null
&& dr.Length > 0){ foreach
(DataRow item in
dr) { temp.Rows.Add(item.ItemArray); }}this.dgv_DataSource.DataSource = temp; |
