我需要你的帮助。我想根据文本框中输入的数字I显示所有数据。在文本框中输入的数字将是我的阈值。我想在表格中显示所有数据"拒绝"超过我对datagridview的门槛。谁能帮我 ?这是我的代码:
if (NominalBox.Text != "")
{
int thresholdcas50;
Int32.TryParse(NominalBox.Text, out thresholdcas50);
koneksi.Open();
System.Data.DataTable aksesdatatabel;
aksesdatatabel = koneksi.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
koneksi.Close();
OleDbCommand command = new OleDbCommand
(
"select Reject from [Sheet1$]", koneksi
);
DataSet coba = new DataSet();
OleDbDataAdapter adapter = new OleDbDataAdapter(command);
adapter.Fill(coba);
// Here I want to read all datas in "Reject" and convert
// them into integer. There is an error here.
// It says "Input string was not in a correct format".
int x = int.Parse(coba.Tables[0].ToString());
if (x > thresholdcas50)
{
// I stuck here. I don't know how to show all datas that
// more than my threshold.
dataGridView1.DataSource = coba.Tables[0];
}
}
任何人都可以帮助我吗?我很困惑,我只能显示超过我的阈值的数据。谢谢

试试这个:
if (NominalBox.Text != "")
{
int thresholdcas50;
Int32.TryParse(NominalBox.Text, out thresholdcas50);
koneksi.Open();
System.Data.DataTable aksesdatatabel;
aksesdatatabel = koneksi.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
koneksi.Close();
OleDbCommand command = new OleDbCommand
(
"select Reject from [Sheet1$]", koneksi
);
DataSet coba = new DataSet();
OleDbDataAdapter adapter = new OleDbDataAdapter(command);
adapter.Fill(coba);
// Just made a variable to quick identify your table.
var table = coba.Tables[0];
// Make a view from your table.
var view = new DataView(table);
// Make a filter on the view.
view.RowFilter = string.Format("Reject > {0}", thresholdcas50);
// Now set the DataSource to your filter.
dataGridView1.DataSource = view;
}
