C#将Excel数据表导入SQL

[EvilsBlood]

代码是在网上摘的，功能是将Excel数据表导入SQL
程序运行报错是无法访问 sheet1

public void TransferData(string excelFile, string sheetName, string connectionString)
{
DataSet ds = new DataSet();
try
{
//获取全部数据
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + excelFile + ";" + "Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
string strExcel = "";
OleDbDataAdapter myCommand = null;
strExcel = string.Format("select * from [{0}$]", sheetName);
myCommand = new OleDbDataAdapter(strExcel, strConn);
myCommand.Fill(ds, sheetName);

//如果目标表不存在则创建
string strSql = string.Format("if object_id('{0}') is null create table {0}(", sheetName);
foreach (System.Data.DataColumn c in ds.Tables[0].Columns)
{
strSql += string.Format("[{0}] varchar(255),", c.ColumnName);
}
strSql = strSql.Trim(',') + ")";

using (System.Data.SqlClient.SqlConnection sqlconn = new System.Data.SqlClient.SqlConnection(connectionString))
{
sqlconn.Open();
System.Data.SqlClient.SqlCommand command = sqlconn.CreateCommand();
command.CommandText = strSql;
command.ExecuteNonQuery();
sqlconn.Close();
}
//用bcp导入数据
using (System.Data.SqlClient.SqlBulkCopy bcp = new System.Data.SqlClient.SqlBulkCopy(connectionString))
{
bcp.SqlRowsCopied += new System.Data.SqlClient.SqlRowsCopiedEventHandler(bcp_SqlRowsCopied);
bcp.BatchSize = 100;//每次传输的行数
bcp.NotifyAfter = 100;//进度提示的行数
bcp.DestinationTableName = sheetName;//目标表
bcp.WriteToServer(ds.Tables[0]);
}
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
}
}

应该是你excel文件里面没有sheet1这个页面，你把sheet1改成已有的页面名称就行了。
