无法读取Excel表格

这很奇怪，我试图用数据读取器访问excel表格，并得到一个我很难弄清楚的错误。 想知道是否有人遇到同样的问题。

Microsoft Office Access数据库引擎找不到对象“SHEETNAME”。 确保对象存在，并且正确拼写其名称和path名称

var str = new StringBuilder(); using (var myConnection = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=foreignkeys.xlsx;Extended Properties='Excel 8.0;HDR=Yes'")) { using (var myCommand = new OleDbCommand()) { myConnection.Open(); myCommand.Connection = myConnection; myCommand.CommandText = "select TableName, ColumnName from [SHEETNAME]"; using (var dr = myCommand.ExecuteReader()) { while (dr.Read()) { var tableName = dr["TableName"].ToString(); var columnName = dr["ColumnName"].ToString(); var tmp = columnName; tmp = tmp.Replace("ID", "").Replace("Id", ""); str.AppendLine(string.Format("IF NOT EXISTS ( SELECT 1 FROM sys.foreign_keys AS FK WHERE name = 'FK_{0}_{1}' AND parent_object_id = OBJECT_ID('{2}'))", tableName, tmp, tableName)); str.AppendLine("BEGIN"); str.AppendLine(string.Format("ALTER TABLE dbo.{0} WITH CHECK", tableName)); str.AppendLine(string.Format("ADD CONSTRAINT FK_{0}_{1} FOREIGN KEY ({2}) REFERENCES dbo.{3}({4})", tableName, tmp, columnName, tmp, columnName)); str.AppendLine("END"); str.AppendLine(""); str.AppendLine(""); } } } } return str.ToString();

假设你的Excel文件包含名为SHEETNAME的表，那么你需要写

  myCommand.CommandText = "select TableName, ColumnName from [SHEETNAME$]"; ^
