LINQ 包含不区分大小写 [英] LINQ Contains Case Insensitive

问题描述

此代码区分大小写，如何使其不区分大小写?

This code is case sensitive, how to make it case insensitive?

public IQueryable<FACILITY_ITEM> GetFacilityItemRootByDescription(string description)
{
    return this.ObjectContext.FACILITY_ITEM.Where(fi => fi.DESCRIPTION.Contains(description));
}

推荐答案

假设我们在这里处理字符串，这里是另一个使用 IndexOf() 的优雅"解决方案.

Assuming we're working with strings here, here's another "elegant" solution using IndexOf().

public IQueryable<FACILITY_ITEM> GetFacilityItemRootByDescription(string description)
{
    return this.ObjectContext.FACILITY_ITEM
        .Where(fi => fi.DESCRIPTION
                       .IndexOf(description, StringComparison.OrdinalIgnoreCase) != -1);
}
