请教有个DataTable

[sanmuncle]

有个DataTable,第一列为主键值，如何根据一个主键值，得到该值位于表中的第几行？

for循环找咯。！！

你可以使用CurrencyMangager类
private CurrencyManager myCurrencyManager;

private void BindControl(DataTable myTable){
// Bind a TextBox control to a DataTable column in a DataSet.
textBox1.DataBindings.Add("Text", myTable, "CompanyName");
// Specify the CurrencyManager for the DataTable.
myCurrencyManager = (CurrencyManager)this.BindingContext[myTable];
// Set the initial Position of the control.
myCurrencyManager.Position = 0;
}

private void MoveNext(CurrencyManager myCurrencyManager){
if (myCurrencyManager.Position == myCurrencyManager.Count - 1){
MessageBox.Show("You're at end of the records");
}
else{
myCurrencyManager.Position += 1;
}
}

private void MoveFirst(CurrencyManager myCurrencyManager){
myCurrencyManager.Position = 0;
}

private void MovePrevious(CurrencyManager myCurrencyManager ){
if(myCurrencyManager.Position == 0) {
MessageBox.Show("You're at the beginning of the records.");
}
else{
myCurrencyManager.Position -= 1;
}
}

private void MoveLast(CurrencyManager myCurrencyManager){
myCurrencyManager.Position = myCurrencyManager.Count - 1;
}

LesleyChiu(鱼头) ：这样是可以实现，数据少还可以，多了感觉有点影响速度。
Stevetan81(Steve) ：CurrencyMangager需要和数据源帮定，但我不希望那样去做。
