Directx 11 - CompileFromFile() is not compiling

所以，我不确定我是否错过了什么。

我有一个着色器类，我想从包含 DirectX 函数D3DCompileFromFile()的函数LoadFromFile()的文件加载和编译着色器，这是执行此操作所需的

void Shader::LoadFromFile(const char* file, const char* vsEntry, const char* psEntry)
{
DXCall(D3DCompileFromFile((LPCWSTR)file, 0, D3D_COMPILE_STANDARD_FILE_INCLUDE, vsEntry, "vs_5_0", 0, 0, &m_vsb, 0));
DXCall(D3DCompileFromFile((LPCWSTR)file, 0, D3D_COMPILE_STANDARD_FILE_INCLUDE, psEntry, "ps_5_0", 0, 0, &m_psb, 0));
DXCall(Renderer::Get()->GetDevice()->CreateVertexShader(m_vsb->GetBufferPointer(), m_vsb->GetBufferSize(), 0, &m_vs));
DXCall(Renderer::Get()->GetDevice()->CreatePixelShader(m_psb->GetBufferPointer(), m_psb->GetBufferSize(), 0, &m_ps));
...
}

我想像这样在 main 中调用该函数

Shader shader;
shader.LoadFromFile("res/Default.hlsl", "VS", "PS");

但是，当它到达创建顶点着色器函数时，我不断收到以下错误：

Exception thrown: read access violation. this->m_vsb was nullptr.

只是找不到文件还是着色器文件中有一些错误的代码？

struct VOut;
{
float4 Position : SV_POSITION;
float4 COLOR : COLOR;
};
VOut VS(float4 position : POSITION, float4 color : COLOR)
{
VOut output;
output.Position = position;
output.Color = color;
return output;
};
float4 PS(VOut input) : SV_TARGET
{
return input.Color;
};
