我正在尝试空白/清除整个 Excel 选项卡。但似乎没有任何效果
我尝试了以下方法:
OleDbConnection connection = new OleDbConnection(connectionString);
OleDbCommand command = new OleDbCommand("Select * FROM [Sheet1$]", connection);
OleDbCommand count = new OleDbCommand("Select count(*) FROM [Sheet1$]", connection);
DataSet dataset = new DataSet();
OleDbDataAdapter adapter = new OleDbDataAdapter();
adapter.SelectCommand = new OleDbCommand("Select * from [Sheet1$]", connection);
adapter.Fill(dataset);
for (int i = 0; i < dataset.Tables[0].Rows.Count; i++)
{
DataRow dtRow = dataset.Tables[0].Rows[i];
foreach (DataColumn col in dataset.Tables[0].Columns)
{
if(col.DataType == typeof(string))
dataset.Tables[0].Rows[i][col] = "";
}
}
dataset.Tables[0].AcceptChanges();
adapter.Update(dataset.Tables[0]);
