ObjectListView 获取特定列的值

Question

我用的是C#和ObjectListView，需要获取具体点击的行列的值。

示例：获取点击的行第 3 列的值。

如何通过 CellClick 做到这一点？

private void treeListView1_CellClick(object sender, CellClickEventArgs e)
{
   ???
}

Answer 1

我只想获取第 3 列的值，无论我在哪里点击。

private void objectListView1_CellClick(object sender, CellClickEventArgs e) {
    // check if it is the column of interest
    if (e.Column == olvColumn3) {
        // method 1: just get the value from the objectListView1 cell, 
        // this potentially requires casting ModelValue to the correct type which can be error prone if the type changes
        object value = e.SubItem.ModelValue;

        // method 2: since you "know" what property of your underlying model is displayed in column 3,
        // you should retrieve it directly from the model object
        MyModel modelObject = (MyModel)e.Model;
        string value2 = modelObject.ValueThatBelongsToColumn3;
    }
}
