关于值类型与列类型不匹配,所需类型是 DataRow"的解决方案

今天,在vs2005下将SqlDataReader 转换为DataTable时,出现了 "值类型与列类型不匹配不能在
ID 列中存储 <30>。所需类型是
DataRow"的错误码,后来查了后,原来是这里的问题,查找相关资料后发现,(把蓝字部分修改成红字部分),修改成功

public static DataTable
ConvertDataReaderToDataTable(OleDbDataReader
dataReader)
       
{
           
//定义DataTable和模式
           
DataTable datatableTemp = new
DataTable();
           
DataTable schemaTable =
dataReader.GetSchemaTable();
           
try
           
{
               
//动态添加表的数据列
               
foreach (DataRow myRow in
schemaTable.Rows)
               
{
                   
DataColumn myDataColum = new DataColumn();

//myDataColum.DataType =
myRow.GetType(); 
                   
myDataColum.DataType =
System.Type.GetType("System.String"); 
                   
myDataColum.ColumnName =
myRow[0].ToString();
                   
datatableTemp.Columns.Add(myDataColum);
               
}

//添加表的数据
               
while
(dataReader.Read())
               
{
                   
DataRow myDataRow =
datatableTemp.NewRow();
                   
for (int i = 0; i < schemaTable.Rows.Count;
i++)
                   
{
                       
myDataRow[i]=
dataReader[i].ToString();
                   
}
                   
datatableTemp.Rows.Add(myDataRow);
                   
myDataRow =
null;
               
}
               
schemaTable =
null;
               
dataReader.Close();
               
return
datatableTemp;
           
}
            catch
(Exception
ex)
           
{
               
throw new Exception(ex.Message,
ex);
           
}

}
