将数据行添加到数据表 [英] Adding datarows to a datatable
问题描述
大家好!
我有一个简单的问题,我现在看不到解决方案。我希望有人可以查明我做错了什么。
主要目标:为数据表创建新的数据行,并为每个数据行添加3列的值。 br />
Hi everyone!
I have a simple issue that I can't see a resolution for right now. I'm hoping someone can pinpoint what I'm doing wrong.
Main goal: Create new datarows for a datatable and add values for 3 columns to each datarow.
DataTable waveform_file_dt = new DataTable();
DataRow newRow = waveform_file_dt.NewRow();
newRow["table_name"] = tl;
newRow["column_name"] = columnQuery_dr.GetString(0);
newRow["waveform_file"] = waveform_comms_dr.GetString(0) + ".psdata";
waveform_file_dt.Rows.Add(newRow);
我看到的错误是:
列table_name不属于表格。
如何引用数据表中列的索引?
(隐藏赋值的注释:tl来自foreach循环,columnQuery_dr.GetString(0)来自SQLCeDataReader检查读取器结束,与waveform_comms_dr.GetString(0)相同)。 />
谢谢大家!
The error I'm seeing is :
Column "table_name" does not belong to table.
How can I reference the index of the column in the datatable?
(Notes for cryptic assignments: "tl" is from a foreach loop, columnQuery_dr.GetString(0) is from a SQLCeDataReader check for end of reader and same with waveform_comms_dr.GetString(0)).
Thank you everyone!
