I want to upload excel data but i don't know the sheet name.

What I have tried:

OleDbConnection connection = null;

try
{
    string excelConnectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 8.0;HDR=Yes'", path);
    connection = new OleDbConnection();
    connection.ConnectionString = excelConnectionString;
    OleDbCommand command = new OleDbCommand("select * from [Sheet1$]", connection);
    connection.Open();
    DbDataReader dr = command.ExecuteReader();
    DataTable table = new DataTable("Customers");
    table.Load(dr);

refer this C# - Retrieve Excel Workbook Sheet Names.[^] to get the sheeetname and iterate from that.

1 solution

Get the sheet names, and you can find it from there: OleDbConnection.GetOleDbSchemaTable Method (Guid, Object[]) (System.Data.OleDb)[^] - the example MS provide retrieves all sheet names.

I used this but this gives me error in query
here is code

OleDbConnection connection = null;

try
{
string excelConnectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 8.0;HDR=Yes'", path);
connection = new OleDbConnection();
connection.ConnectionString = excelConnectionString;
connection.Open();
DataTable table = new DataTable("Customers");
table = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
String[] excelSheets = new String[table.Rows.Count];
int i = 0;

// Add the sheet name to the string array.
foreach (DataRow row in table.Rows)
{
excelSheets[i] = row["TABLE_NAME"].ToString();
i++;
}
string Sheet = excelSheets[1];

string query = "select * from" + Sheet;
OleDbCommand command = new OleDbCommand(query, connection);

DbDataReader dr = command.ExecuteReader();

table.Load(dr);

And did you use the debugger to look at exactly what was going on?
What did it show you?

The query problem is solved but it add some additional columns in table like Table_catalog,table_schema,table type
