對於問題:
這些步驟是如何得到預期的數據:
- 閱讀從Excel文件中的所有數據需要知道
Sheet Name
;
- 過濾無效數據,因爲有很多列值是
empty
,null
或space-string
但添加到行;使用Linq
- 查詢數據。
希望我的回答可以幫助你。
參考代碼:
public void Test()
{
string filePath = $"{Environment.CurrentDirectory}//test20170206.xls";
string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filePath + ";Extended Properties='Excel 8.0;HDR=NO;IMEX=1;'";
//connection excel
OleDbConnection conn = new OleDbConnection(conStr);
conn.Open();
//get all sheel from excel file
DataTable tb = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
foreach (DataRow row in tb.Rows)
{
Console.WriteLine(row["TABLE_NAME"]);
//using index in row
for (int i=0;i p.Datetime).ToLongTimeString(), TimeMax = g.Max(p => p.Datetime).ToLongTimeString() };
}
public class Model20170206
{
public int Id { get; set; }
public DateTime Datetime { get; set; }
public string Value1 { get; set; }
public string Value2 { get; set; }
public string Value3 { get; set; }
public string Value4 { get; set; }
}
