在DataTable中查找值

DataTable dataTable = new DataTable();
// 假设dataTable已经包含了数据
string searchValue = "查找的值";
DataRow[] foundRows = dataTable.Select($"ColumnName = '{searchValue}'");

DataTable dataTable = new DataTable();
// 假设dataTable已经包含了数据
string searchValue = "查找的值";
DataRow foundRow = dataTable.Rows.Find(searchValue);

DataTable dataTable = new DataTable();
// 假设dataTable已经包含了数据
string searchValue = "查找的值";
var foundRows = dataTable.AsEnumerable().Where(row => row.Field<string>("ColumnName") == searchValue);
