在.NET核心中使用DbModelBuilder来指定命名约定

ModelBuilder 允许类似的功能:

var keyProperties = modelBuilder
    .Model
    .GetEntityTypes()
    .SelectMany(e => e.GetProperties())
    .Where(p => p.Name == p.DeclaringEntityType.ClrType.Name + "_ID")
    .ToList();

foreach (var p in keyProperties)
{
    modelBuilder
        .Entity(p.DeclaringEntityType.Name)
        .HasKey(p.Name);
}

它内置在ModelBuilder中。

呼叫 modelBuilder.Model.GetEntityTypes()

要更改表名,请使用以下代码行

entityType.Relational().TableName = ConvertToUpperCaseUnderscore(entityType.ClrType.Name);

要使用相同的约定将属性映射到列,请调用 entityType.GetProperties()

因此,总体使用情况是

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    foreach (var entityType in modelBuilder.Model.GetEntityTypes())
    {
        if (entityType.ClrType == null)
        {
            continue;
        }

        // Set the table name mapping for the class
        entityType.Relational().TableName = ConvertToUpperCaseUnderscore(entityType.ClrType.Name);

        var props = entityType.GetProperties().ToList();

        foreach (var p in props)
        {
            // Set the column name mapping for the class
            p.Relational().ColumnName = ConvertToUpperCaseUnderscore(p.Name);
        }
    }

    base.OnModelCreating(modelBuilder);
}
