# FunctionsDI
[](https://www.nuget.org/packages/RSCG_FunctionsWithDI)
Generate (constructor) and functions calls similar with ASP.NET Core WebAPI ( [FromServices] will be provided by DI )
Also, verifies for null .
# Usage 1 - generate constructors from methods
Reference into the csproj
```xml
true
$(BaseIntermediateOutputPath)GeneratedX
```
Then for every class you can write [FromServices]
```csharp
using RSCG_FunctionsWithDI_Base;
//namespace if necessary
public partial class TestDIFunction
{
public bool TestMyFunc1([FromServices] TestDI1 t1, [FromServices] TestDI2 t2, int x, int y)
{
return true;
}
//more functions
}
```
generates the constructor with needed details
```csharp
public partial class TestDIFunction
{
private TestDI1 _TestDI1;
private TestDI2 _TestDI2;
public TestDIFunction (TestDI1 _TestDI1,TestDI2 _TestDI2) //constructor generated with needed DI
{
this._TestDI1=_TestDI1;
this._TestDI2=_TestDI2;
} //end constructor
//making call to TestMyFunc1
public bool TestMyFunc1(int x,int y){
var t1 = this._TestDI1 ;
if(t1 == null) throw new ArgumentException(" service TestDI1 is null in TestDIFunction ");
var t2 = this._TestDI2 ;
if(t2 == null) throw new ArgumentException(" service TestDI2 is null in TestDIFunction ");
return TestMyFunc1(t1,t2,x,y);
}
```
so you can call
```csharp
var test=serviceProvider.GetService();
Console.WriteLine(test.TestMyFunc1(10,3)); // calling without the [FromServices] arguments
```
# Usage 2 - generate constructors from fields / constructors
```xml
true
$(BaseIntermediateOutputPath)GeneratedX
```
Assuming this classes, that you want to keep a minimum of parameters constructors
```csharp
public partial class TestDIFunctionAdvWithConstructor
{
[RSCG_FunctionsWithDI_Base.FromServices]
private TestDI1 NewTestDI1;
[RSCG_FunctionsWithDI_Base.FromServices]
public TestDI2 NewTestDI2 { get; set; }
public readonly TestDI3 myTestDI3;
private TestDIFunctionAdvWithConstructor(TestDI3 test)
{
myTestDI3= test;
}
}
public partial class TestDIFunctionAdvNoConstructor
{
[RSCG_FunctionsWithDI_Base.FromServices]
public TestDI1 NewTestDI1;
[RSCG_FunctionsWithDI_Base.FromServices]
private TestDI2 NewTestDI2 { get; set; }
}
```
the generator will generate
```csharp
namespace TestFunctionsWithDI
{
public partial class TestDIFunctionAdvNoConstructor
{
public TestDIFunctionAdvNoConstructor( TestDI1 _NewTestDI1,TestDI2 _NewTestDI2 )
{
this.NewTestDI1 = _NewTestDI1;
this.NewTestDI2 = _NewTestDI2;
}//end constructor
}//class
}//namespace
namespace TestFunctionsWithDI
{
public partial class TestDIFunctionAdvWithConstructor
{
public TestDIFunctionAdvWithConstructor(TestDI3 test, TestDI1 _NewTestDI1, TestDI2 _NewTestDI2) : this (test)
{
this.NewTestDI1 = _NewTestDI1;
this.NewTestDI2 = _NewTestDI2;
}//end constructor
}//class
}//namespace
```
Enjoy!
