导入任何Excel电子表格到DataGridView – C＃

我有一个程序，将excel电子表格导入到datagridview。 我写的代码如下：

try { OleDbConnectionStringBuilder connStringBuilder = new OleDbConnectionStringBuilder(); connStringBuilder.DataSource = file; connStringBuilder.Provider = "Microsoft.Jet.OLEDB.4.0"; connStringBuilder.Add("Extended Properties", "Excel 8.0;HDR=NO;IMEX1"); DbProviderFactory factory = DbProviderFactories.GetFactory("System.Data.OleDb"); DbDataAdapter adapter = factory.CreateDataAdapter(); DbCommand selectCommand = factory.CreateCommand(); selectCommand.CommandText = "SELECT * FROM [All Carpets to Excel$]"; DbConnection connection = factory.CreateConnection(); connection.ConnectionString = connStringBuilder.ConnectionString; selectCommand.Connection = connection; adapter.SelectCommand = selectCommand; data = new DataSet(); adapter.Fill(data); dataGridView1.DataSource = data.Tables[0].DefaultView; } catch (IOException) { } 

“selectCommand.CommandText =”SELECT * FROM [All Carpets to Excel $]“;” 从该名单的工作表中获取数据。 我想知道如何让这个程序打开任何工作表名称的Excel文档。 我可能不知道的一个。

提前致谢！

你可以得到所有的名单像这样..

 public string[] GetExcelSheetNames(string excelFileName) { OleDbConnection con = null; DataTable dt = null; String conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + excelFileName + ";Extended Properties=Excel 8.0;"; con= new OleDbConnection(conStr); con.Open(); dt = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); if (dt == null) { return null; } String[] excelSheetNames = new String[dt.Rows.Count]; int i = 0; foreach (DataRow row in dt.Rows) { excelSheetNames[i] = row["TABLE_NAME"].ToString(); i++; } return excelSheetNames; }
