如何从ComboBoxC#Winforms获取ValueMember值？我在尝试获取我设置的ValueMember值时遇到了一些问题。我正在尝试使用组合框来选择Windows窗体报告。我可以获得名称而不是RptValue。这是我的代码：privateclassData{publicstringName{get;放;}publicstringRptValue{get;放;}}privatevoidBaseForm_Load(objectsender,EventArgse){this.rvDoctorReportViewer.RefreshReport();comboBox1.Items.Add(新数据{Name="Select",RptValue="Select"});comboBox1.Items.Add(newData{Name="AllFoodValues",RptValue="AllFoodValues.rdlc"});comboBox1.Items.Add(newData{Name="AllReadings",RptValue="AllReadings.rdlc"});comboBox1.Items.Add(newData{Name="AvgFoodValuesbyDate",RptValue="AvgFoodValuesByDate.rdlc"});comboBox1.Items.Add(newData{Name="AvgFoodValuesbyMeal",RptValue="AvgFoodValuesByMeal.rdlc"});comboBox1.Items.Add(newData{Name="AvgReadingsbyDate",RptValue="AvgReadingsByDate.rdlc"});comboBox1.Items.Add(newData{Name="AvgReadingsbyTime",RptValue="AvgReadingsByTime.rdlc"});comboBox1.Items.Add(newData{Name="AvgReadingsbyEvent",RptValue="AvgReadingsByEvent.rdlc"});comboBox1.Items.Add(newData{Name="血压图表",RptValue="BPChart.rdlc"});comboBox1.Items.Add(newData{Name="血压报告",RptValue="BPReport.rdlc"});comboBox1.Items.Add(newData{Name="DetailFoodValuesbyMeal",RptValue="DetailFoodValuesByMeal.rdlc"});comboBox1.Items.Add(newData{Name="医生详细报告",RptValue="DoctorDetailReport.rdlc"});comboBox1.Items.Add(newData{Name="FoodChart",RptValue="FoodChart.rdlc"});comboBox1.Items.Add(newData{Name="PumperDetailReport",RptValue="PumperDetailReport.rdlc"});comboBox1.Items.Add(newData{Name="ReadingCharts",RptValue="ReadingCharts.rdlc"});comboBox1.Items.Add(newData{Name="TotalDailyFoodIntake",RptValue="TotalIntakeDailyFood.rdlc"});comboBox1.DisplayMember="Name";//这很好用comboBox1.ValueMember="RptValue";//这是问题。它呈现为RptValue而不是值comboBox1.SelectedIndex=0;}privatevoidcomboBox1_SelectedIndexChanged(objectsender,EventArgse){if(comboBox1.SelectedIndex>0){stringstrReport;strReport="报表查看器。"+comboBox1.ValueMember.ToString();rvDoctorReportViewer.Reset();rvDoctorReportViewer.LocalReport.ReportEmbeddedResource=strReport;this.rvDoctorReportViewer.RefreshReport();您应该使用DataSource属性试试这个：BindingList_comboItems=newBindingList();_comboItems.Add(newData{Name="Select",RptValue="Select"});_comboItems.Add(newData{Name="AllFoodValues",RptValue="AllFoodValues.rdlc"});...comboBox1.DataSource=_comboItems;comboBox1.DisplayMember="名称";comboBox1.ValueMember="RptValue";然后访问选中的值：strReport="ReportViewer."+comboBox1.SelectedValue;字符串;s=comboBox1.SelectedValue.tostring()这对我有用：以上是C#学习教程：如何从ComboBoxC#Winforms获取ValueMember值？分享的所有内容，如果对你有用，需要了解更多C#学习教程，希望大家多多关注——combobox.valuemember="id"combobox.displaymember="name"combobox.datasource=dt这个文章来自网络合集，不代表立场，如涉及侵权，请点击右边联系管理员删除。如需转载请注明出处：
