隐藏组合框一个项目在C＃

Question

目标保管会员组：

cboDestinationVault.DataSource = Enum.GetValues(typeof(enumVaultType)) 
     .Cast<enumVaultType>() 
     .Select(x => new { 
      Value = x, Description = x.ToString().Replace("_", " ") 
     }).ToList(); 

cboDestinationVault.DisplayMember = "Description"; 

cboDestinationVault.ValueMember = "Value"; 

我想隐藏cboDestinationVault一个项目。

只需添加一个Where子句您Linq声明

cboDestinationVault.DataSource = Enum.GetValues(typeof(enumVaultType)) 
     .Cast<enumVaultType>() 
     .Where(e => e != enumVaultType.Whatever) 
     .Select(x => new { 
      Value = x, Description = x.ToString().Replace("_", " ") 
     }).ToList(); 

如果有不止一个，你可以使用Except

cboDestinationVault.DataSource = Enum.GetValues(typeof(enumVaultType)) 
     .Cast<enumVaultType>() 
     .Except(new []{enumVaultType.ThisOne, enumVaultType.ThatOne}) 
     .Select(x => new { 
      Value = x, Description = x.ToString().Replace("_", " ") 
     }).ToList();
