/// <summary>查找dataTable表

/// </summary>
/// <param name="strFilter">过滤语句</param>
/// <param name="orginalDt">dataTable</param>
/// <returns></returns>
public static DataTable FilterDataTable(string strFilter, DataTable orginalDt)
{
DataRow[] drArr = orginalDt.Select(strFilter);
DataTable newDt = new DataTable();
newDt = orginalDt.Clone();
for (int i = 0; i < drArr.Length; i++)
{
newDt.ImportRow(drArr[i]);
}
return newDt;
}

string strFilter=@"姓名 like '王%'" //查找姓名列的王姓人员
dataGridView.DataSource=FilterDataTable(strFilter,myDt) //myDt是你原先的datatable
