推荐答案

您需要将新创建的dataGridView1添加到表单中。 You need to add newly create dataGridView1 to your form. dataGridView1.DataSource = dataTable1; this.Controls.Add(dataGridView1);

我不确定你的文本文件数据是如何排列的，但看起来你做错了。例如，如果您有如下文本文件

I'm not sure how your text file data arranged, but it seems you are doing it wrong way. for example if you have text file like below

Column1,Column2 data11,data12 data21,data22

然后你的代码应该如下

then your code should be like below

DataTable dataTable1 = new DataTable(); foreach (string header in headers) dataTable1.Columns.Add(header, typeof(string), null); for (int i = 1; i < textData.Length; i++) dataTable1.Rows.Add(textData[i].Split(','));

1.请注意，添加数据已开始来自索引1（第二行） 2.添加行数据时，您可以拆分并设置每列的值，否则行内容将仅分配给第一列。

1. note that, adding data started from index 1 (second row) 2. when adding row data you can split and set values for each column, otherwise line content will assign to first column only.
