复制代码 代码如下:
public static DataTable UniteDataTableColumns(DataTable dt, String newColumnName, string ColumnName1, string ColumnName2)
{
//汇总的表达式
string expression = "";
expression = String.Format("{0}+'('+{1}+')'", ColumnName1, ColumnName2);
//增加汇总列
System.Type myDataType = System.Type.GetType("System.String");
DataColumn dcCol = new DataColumn(newColumnName, myDataType, expression, MappingType.Attribute);
//增加合并列
dt.Columns.Add(dcCol);
return dt;
}
