虽然迟到了，但我是LinqToExcel的粉丝

SpreadsheetGear for . net是一个Excel兼容的电子表格组件。您可以在我们产品页面的右侧看到我们的客户对性能的评价。您可以自己尝试使用免费的、功能齐全的评估。

var fileName = string.Format("{0}\\fileNameHere", Directory.GetCurrentDirectory());
var connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", fileName);

var adapter = new OleDbDataAdapter("SELECT * FROM [workSheetNameHere$]", connectionString);
var ds = new DataSet();

adapter.Fill(ds, "anyNameHere");

DataTable data = ds.Tables["anyNameHere"];

这是我常用的。这有点不同，因为我通常在表的编辑处使用AsEnumerable():

var data = ds.Tables["anyNameHere"].AsEnumerable();

因为这让我使用LINQ从字段中搜索和构建结构。

var query = data.Where(x => x.Field<string>("phoneNumber") != string.Empty).Select(x =>
                new MyContact
                    {
                        firstName= x.Field<string>("First Name"),
                        lastName = x.Field<string>("Last Name"),
                        phoneNumber =x.Field<string>("Phone Number"),
                    });

接受。io电子表格将为您做这个工作，并且不收费。看看这个。

以下是几年前我用。net 1.1用c#编写的一些代码。不确定这是否正是你所需要的(可能不是我最好的代码:))。
