c# - 在 C# 中隐藏组合框中的一项

Question

目标库成员集:

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

cboDestinationVault.DisplayMember = "Description";

cboDestinationVault.ValueMember = "Value";

我想从 cboDestinationVault 中隐藏一项。

Answer 1

只需在 Linq 语句中添加一个 Where 子句

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

如果有多个你可以使用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();
