数据集就像一个内存数据库。这可以包含一个或多个表。获取检索到的值从你的excel文件中，你应该进入它的表并访问那里的单元格。



由于你的select查询只返回excel文件中的一个单元格，你可能以这种方式从数据集中访问值。

A dataset is like a in-memory database. This can contain one or more tables. To get the retrieved value from your excel file, you should go inside its table and access the cell there.

Since your select query there returns only one cell from the excel file, you can probably access the value from the dataset this way.

Label1.Text = ds.Tables[0].Rows[0][0].ToString(); //On the [0][0] part, the first index refers to the row index while the second refers to the column index

更新：



似乎它将值视为标题列。我尝试了你的代码并对连接字符串进行了一些修改，只添加了HDR = NO。您可以尝试下面的代码。

UPDATE:

It seems that it's treating the value as a header column. I tried your code and made some modifications on the connection string, just added HDR=NO. You may try the code below on your end.

string connStr = String.Format(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=""Excel 8.0;HDR=NO;""", file);
