Reading SQLite table information in C#.NET

Question

I would like to read the table and column information in C#.NET Windows application. I know that there is SMO base access for SQL Server. On similar ground is there any API for SQLite?

You can use the GetSchema method :

DbProviderFactory factory = DbProviderFactories.GetFactory("System.Data.SQLite");
using (DbConnection connection = factory.CreateConnection())
{
    connection.ConnectionString = @"Data Source=D:\tmp\test.db";
    connection.Open();
    DataTable tables = connection.GetSchema("Tables");
    DataTable columns = connection.GetSchema("Columns");
    tables.Dump();
    columns.Dump();
}

GetSchema returns a DataTable that contains information about the tables, columns, or whatever you specify. Valid GetSchema arguments for SQLite include:

• MetaDataCollections
• DataSourceInformation
• DataTypes
• ReservedWords
• Catalogs
• Columns
• Indexes
• IndexColumns
• Tables
• Views
• ViewColumns
• ForeignKeys
• Triggers
