读取Excel文件内容到DataSet

读取Excel文件内容到DataSet

用途：快速读取Excel数据

特点：使用内部引擎读，不需安装Excel，读取不会启动Excel的进程

DataSet ds = null;

string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source= " + fileName + ";Extended Properties='Excel "

+ (fileName.EndsWith("xls", StringComparison.CurrentCultureIgnoreCase) ? "8" : "12") + ".0;HDR=" + (isFirstTitle ? "Yes" : "No") + "'";

using (OleDbConnection conn = new OleDbConnection(strConn))

{

conn.Open();

//返回Excel的架构，包括各个sheet表的名称,类型，创建时间和修改时间等

DataTable dtSheetName = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] { null, null, null, "Table" });

ds = new DataSet();

//包含excel中表名的字符串数组

for (int k = 0; k < dtSheetName.Rows.Count; k++)

{

string strTableName = dtSheetName.Rows[k]["TABLE_NAME"].ToString();

string str = "select * from [" + strTableName + "]";

OleDbDataAdapter da = new OleDbDataAdapter(str, conn);

da.Fill(ds, strTableName.Replace("$", "").ToLower());

da.Dispose();

}

conn.Close();

conn.Dispose();
