Quick Start

1. Install the latest Cesil off of Nuget.
   • If you want to avoid runtime code generation, you will need to add Cesil.SourceGenerator as well. See Source Generators for more details.
2. Add using Cesil; to your C# file
3. Create a configuration (with default Options) with either Configuration.For<TYourType>() or Configuration.ForDynamic(), as appropriate for your use case
4. Create a reader or writer using one of the CreateReader, CreateAsyncReader, CreateWriter, or CreateAsyncWriter methods on the configuration.
   • Each of these methods has a number of overloads, supporting using TextReaders, Pipes, and so on.
5. Use the methods on the IReader<TRow>, IAsyncReader<TRow>, IWriter<TRow>, or IAsyncWriter<TRow> interface to read or write your data.

Example: Reading Synchronously

Using a convient method:

using Cesil;

// ...

IEnumerable<MyType> rows = CesilUtils.Enumerate<MyType>(/*Some TextReader*/);

In a more explicit, and configurable, way using explicit configuration and options.

using Cesil;

// ...

Options myOptions = /* ... */
IBoundConfiguration<MyType> myConfig = Configuration.For<MyType>(myOptions);

using(TextReader reader = /* ... */)
using(IReader<MyType> csv = myConfig.CreateReader(reader))
{
    IEnumerable<MyType> rows = csv.EnumerateAll();
}

For more detail, see Reading.

Example: Reading Asynchronously

Using a convient method:

using Cesil;

// ...

IAsyncEnumerable<MyType> rows = CesilUtils.EnumerateAsync<MyType>(/*Some TextReader*/);

In a more explicit, and configurable, way using explicit configuration and options.

using Cesil;

// ...

Options myOptions = /* ... */
IBoundConfiguration<MyType> myConfig = Configuration.For<MyType>(myOptions);

using(TextReader reader = /* ... */)
await using(IAsyncReader<MyType> csv = myConfig.CreateAsyncReader(reader))
{
    IAsyncReader<MyType> rows = csv.EnumerateAllAsync();
}

For more detail, see Reading.

Example: Writing Synchronously

Using a convient method:

using Cesil;

// ...

IEnumerable<MyType> myRows = /* ... */

using(TextWriter writer = /* .. */)
{
    CesilUtilities.Write(myRows, writer);
}

In a more explicit, and configurable, way using explicit configuration and options.

using Cesil;

// ...

IEnumerable<MyType> myRows = /* ... */

Options myOptions = /* ... */
IBoundConfiguration<MyType> myConfig = Configuration.For<MyType>(myOptions);

using(TextWriter writer = /* ... */)
using(IWriter<MyType> csv = myConfig.CreateWriter(writer))
{
    csv.WriteAll(myRows);
}

For more detail, see Writing.

Example: Writing Asynchronously

Using a convient method:

using Cesil;

// ...

// IAsyncEnumerable<MyType> will also work
IEnumerable<MyType> myRows = /* ... */

using(TextWriter writer = /* .. */)
{
    await CesilUtilities.WriteAsync(myRows, writer);
}

In a more explicit, and configurable, way using explicit configuration and options.

using Cesil;

// ...

// IAsyncEnumerable<MyType> will also work
IEnumerable<MyType> myRows = /* ... */

Options myOptions = /* ... */
IBoundConfiguration<MyType> myConfig = Configuration.For<MyType>(myOptions);

using(TextWriter writer = /* ... */)
await using(IWriter<MyType> csv = myConfig.CreateAsyncWriter(writer))
{
    await csv.WriteAllAsync(myRows);
}
