AE+C#：实现ArcMap中打开图层属性表后按属性选择的功能(2)

if (this.field_listBox.SelectedIndex != -1) {

UniqueValueClass uniqueVaueCls = new UniqueValueClass();

list = uniqueVaueCls.GetLayerUniqueFieldValueByDataStatistics( featClsInfo.FeatureClass, this.field_listBox.SelectedItem.ToString());

this.uniqueValue_listBox.Items.Clear(); foreach (var f in list) {

this.uniqueValue_listBox.Items.Add(f); } } }

private void field_DoubleClick(object sender, EventArgs e) {

sql_textBox.Text += field_listBox.SelectedItem.ToString(); }

private void uniqueValue_DoubleClick(object sender, EventArgs e) {

IField field = _fInfo.FeatureClass.Fields.get_Field(field_listBox.SelectedIndex); if (field.Type == esriFieldType.esriFieldTypeString) {

sql_textBox.Text += \+uniqueValue_listBox.SelectedItem.ToString()+\; } else {

sql_textBox.Text += uniqueValue_listBox.SelectedItem.ToString(); } }

private void clear_button_Click(object sender, EventArgs e) {

sql_textBox.Text = \; }

private void apply_button_Click(object sender, EventArgs e) {

this.DialogResult = DialogResult.OK; this.Close();

}

private void close_button_Click(object sender, EventArgs e) {

this.DialogResult = DialogResult.Cancel; this.Close(); }

} }

5、在主窗口事件中调用：

List featClsInfoList = findFeatureLayer();

if (featClsInfoList.Count > 0) {

//打洙?开a查é询ˉ窗洹?口ú frmQueryFeat queryFeatForm = new frmQueryFeat(featClsInfoList.ToArray());

if (queryFeatForm.ShowDialog() == DialogResult.OK) {

int lyrindex = queryFeatForm.LayerIndex();//要癮查é询ˉ的?图?层?

string sql = queryFeatForm.SQL();//查é询ˉ语?句?

IFeatureLayer featureLyr =

axMapControl1.Map.get_Layer(lyrindex) as IFeatureLayer;

searchSelection(sql, featureLyr);//执′行D查é询ˉ } } else {

MessageBox.Show(\缺ā?少Θ?要癮素?图?层?！?\, \提??示?\, MessageBoxButtons.OK, MessageBoxIcon.Information); } }
