问一个DataTable 写入XML文件的问题
一个DataTable其中一列是bool类型，将其写入XML文件后在读出，
该列变成了字符串类型，ture -> "true " ; false -> "false "
如何才能控制该列其读出也为bool类型？（不要遍历赋值）
代码如下：
DataTable tab = new DataTable( "ResistInfo ");

tab.Columns.Add( "Check ", typeof(bool));
tab.Columns.Add( "Name ", typeof(string));

DataRow row = tab.NewRow();
row[ "Check "] = true;
row[ "Name "] = "ggg ";
tab.Rows.Add(row);

row = tab.NewRow();
row[ "Check "] = false;
row[ "Name "] = "fffff ";
tab.Rows.Add(row);

tab.WriteXml( "regeist.xml ");

DataSet newSet = new DataSet();
newSet.ReadXml( "regeist.xml ");

[解决办法]
DataTable redTable = tab.Clone();
redTable.ReadXml( "regeist.xml ");

-------------------------------------------
+redTable.Columns[0].DataType{Name = "Boolean " FullName = "System.Boolean "}System.Type {System.RuntimeType}
